CSI's William Petersen: ''I Won't Miss Grissom"

By GINA DINUNNO
TV GUIDE

Come Jan. 15, television's most popular show, CSI, will lose its beloved character Gil Grissom. But why would William Petersen leave his starring role on a hit show that averages 21.3 million viewers a week? A character that made him one of the highest paid actors on television?

"The reason I'm leaving is because I'm afraid I'm becoming too comfortable,'' Petersen told Entertainment Weekly. ''It's CSI - they pay me a lot of money, and I don't have to work very hard anymore. I've got it all figured out. And I just realized, God, as an artist, I'm going to atrophy. You do anything for nine years, it becomes somewhat rote. I didn't want to be on the show because they were paying me money and I liked the money. I didn't want to be on the show because it saved me from having to go look for other jobs. Just didn't want it. It was too safe for me at this point. So I needed to try and break that, and the way to do that, for me, is the theater.''

But after nine seasons, saying goodbye to Grissom must take its toll on the emotions, right? Not quite. ''I won't miss Grissom,'' Petersen told the magazine. ''It was a complete life for me that's reached its end, and it's reached it in the right way, I think. So I won't miss Grissom. And I hope that the audience won't miss him either.''

Petersen did admit there is one thing he'll miss about playing Grissom - hair fibers. Well, maybe not so much the fibers as those sans-dialogue moments. ''I used to bitch about it a lot the first few years, but I became very adept at having the camera see the fiber, and using the tweezers to pick the fiber up, and then having the camera follow the tweezers to my face so the audience can say, 'Oh, Grissom sees it. He knows what it is.' I'll miss that.''

Now living in Chicago and performing at the Steppenwolf Theater, the 55-year-old actor officially began his goodbye back in November 2007, when Grissom's fiancée hit the road, and continued through the following year with the murder of Warrick (Gary Dourdan) in October 2008. Petersen's exit was ultimately postponed due to the writers' strike, leaving the creative team ample time to fill the void left by Grissom's departure by casting Laurence Fishburne as Raymond Langston.

雖然他說他不會懷念Grissom這個角色，因為他覺得他已經完整的詮釋並交代出這個角色的完整性，

但是，我還是會懷念他的！！

他說他離開是因為，他感到自己在這樣環境，和優渥的薪水條件下（名利雙收了呀！），感到太過安適，而怕自己一直停留在那樣的階段。（真是有演員的自覺）他渴望自己能再有點突破，打破現狀。（不過，還真是有勇氣，很多人在這樣的狀況下，已經於願足矣了吧！）

'CSI' Exclusive: William Petersen Says Goodbye

In his only interview, the man behind Gil Grissom talks about why he's going and what it means for his future -- and for the series
Here's a recently shot scene from an upcoming episode of CSI. The setting: a somber courtroom, where a prominent Nevada congressman stands accused of a beautiful young woman's murder. In the front row sits Catherine Willows (Marg Helgenberger), sheathed in a low-cut blouse and tight pants. Hmmm...upon examining the evidence, there appears nothing out of the ordinary here. But wait, someone's moving into the witness box to testify about the case... Uh, is that Morpheus from The Matrix wearing a pinstripe suit and tie?

Yes, something is definitely off with TV's most popular drama. What's missing, of course, is William Petersen, a.k.a. Gil Grissom - a character so beloved by his audience that CSI, nine seasons in, is still the No. 1 scripted show on television, averaging 21.3 million viewers per week. Petersen, however, is now living some 1,700 miles away in Chicago, where he's resumed a career as a theater actor, playing to audiences of only 300 people. With his final CSI episode set to air 
Jan. 15 on CBS, Petersen is saying goodbye to the show and character that made him very, very famous and very, very rich. For nine years, he's had it all. And that was exactly the problem. ''The reason I'm leaving is because I'm afraid I'm becoming too comfortable,'' says Petersen. ''It's CSI - they pay me a lot of money, and I don't have to work very hard anymore. I've got it all figured out. And I just realized, God, as an artist, I'm going to atrophy. You do anything for nine years, it becomes somewhat rote. I didn't want to be on the show because they were paying me money and I liked the money. I didn't want to be on the show because it saved me from having to go look for other jobs. Just didn't want it. It was too safe for me at this point. So I needed to try and break that, and the way to do that, for me, is the theater.''

 Leaving fame and fortune behind in the name of artistic integrity? There's a novel concept for Hollywood. But still, isn't he just a little sentimental about parting ways with a character that has defined him since 2000? ''I won't miss Grissom,'' says Petersen matter-of-factly. ''It was a complete life for me that's reached its end, and it's reached it in the right way, I think. So I won't miss Grissom. And I hope that the audience won't miss him either.''

There is one thing Petersen will miss about playing the quirky sleuth. It's not the national spotlight, the eight-figure salary, or the adoration of fans. ''Hair fibers,'' he says. He's kidding - sort of. Relaxing between performances at Chicago's Steppenwolf Theatre, where the 55-year-old recently starred as a lonely undertaker in Conor McPherson's Dublin Carol, Petersen says that over time, he begrudgingly grew to respect the show's dialogue-free moments. ''I used to bitch about it a lot the first few years, but I became very adept at having the camera see the fiber, and using the tweezers to pick the fiber up, and then having the camera follow the tweezers to my face so the audience can say, 'Oh, Grissom sees it. He knows what it is.' I'll miss that.''

Actually, he's walking away from a lot more than the maddening minutiae CSI fans love. A producer on the drama since its debut in 2000 and an exec producer since 2004, 
Petersen is one of the highest-paid actors on television (earning a reported $600,000 per episode). Over the years, he's watched his show turn into a ratings powerhouse and a veritable industry for CBS, which will no doubt feel the pain of Petersen's departure. CSI is the backbone of a three-show franchise: Its reruns air in some 200 territories (yep, they even recognize Petersen in Tahiti). The show reportedly commands north of $250K per 30-second spot of commercial time, and with all the syndication and spin-offs, the entire CSI franchise generates ''billions'' in revenue for the network and studio, according to a CBS source.

Naturally, then, it was Petersen - and not producers or the network - who decided when and where Grissom would finally step outside the yellow tape. As he literally notched the passing of each season on his trailer ceiling, the star began hinting to the writers about an expiration date around the 100th episode. ''For years, Billy had been saying he wanted to go, so we knew that one day he'd ask to be written out,'' says Mendelsohn. ''We had a game plan for a long time.'' Petersen and the writers were set on hammering out an exit strategy that would seem organic to the world of forensic science. That's where the real-life Grissoms came into play. ''You talk to all of the CSIs we know, and they all have a short [career] life,'' says Petersen. ''They can do this for a while and then they all try to become techs for our show! None of them want to go back down an alley and process fingerprints on a garbage can anymore.''

The long goodbye officially began in November 2007, when Gil's fiancée Sara (Jorja Fox) fled Las Vegas for destinations unknown, and it continued with the tragic shooting death of Warrick (Gary Dourdan) in October of the following year. ''That's what kicked everything off for Grissom, to begin his journey to wherever he's going because [Warrick's death] was a massive shock to his system,'' explains Petersen. In fact, Petersen should have been gone by now: Warrick's death and Grissom's swan song were originally scheduled to air 
by last May, but the 100-day writers' strike shortened the season, so there wasn't enough time to tell all the stories 
 Petersen wanted - including the return of the Miniature 
Serial Killer and Melinda Clarke's dominatrix, Lady Heather.

Postponing his farewell not only put some much-needed space between the high-profile exits of Fox and Dourdan, it also gave the show's creative team plenty of time to find Petersen's successor. And for the first time in his nearly nine-year run as the king of CSI, Petersen stepped back and let producers make the decision. After putting out feelers to an impressive roster of stars (imagine seeing Kurt Russell or John Malkovich in a lab coat and safety goggles!), the producers set their sights on the aforementioned Morpheus, a.k.a. Laurence Fishburne, who hasn't starred on TV since playing Cowboy Curtis on Pee-wee's Playhouse back in the '80s.

First things first, though: The man with the funny beard still has to take his final bow. If fans were to follow the clues this season, all those private moments of reflection and despair suggest that Gil regrets allowing Sara to get away. But a scene in this season's fifth episode, in which Sara sent an upbeat video message intimating that her life was actually fine without him, could mean that his ex-fiancée won't be so receptive to a reunion. An even bigger cliff-hanger than how Grissom will leave, however, is what will happen to the show after he's gone. ''I'm sick he is leaving,'' says one EW.com poster named Betty. ''CSI is Gil.'' Jasmine puts it more bluntly: ''Once Grissom is gone from the original CSI, so am I.''

Mendelsohn, who cops to frequenting the blogs, doesn't hide her concern. ''I do care what they think,'' she concedes. ''But all you have as a writer are your instincts...and we always thought Grissom having a life outside of CSI is where we were going to take him.'' As he looks forward to the next chapter in his 
career, Petersen hopes viewers will adopt his attitude about Grissom's exit: no tears necessary. ''I think there's a way for the audience to remember him, like losing a great co-worker they've known for years,'' says the actor, who hasn't ruled out starring in another TV show - someday. ''He didn't die in a plane crash, he didn't get a brain tumor. He's out there.''

When Petersen's final day of shooting arrived on Oct. 10, about 200 members of the show's cast and crew assembled on the CSI soundstage to watch his character's last stroll through the dimly lit lab. Though everyone knew that Petersen wasn't gone forever - he'll retain his producer title and he's promised to return for the occasional episode, though that probably won't occur until next season - it didn't make his departure any less significant. ''It was really like a death,'' recalls Mendelsohn, who says she caught a bad cold as a result of the stress. ''It was traumatic.'' Helgenberger can't even think about the ''painful'' day without tearing up. ''I couldn't stop crying,'' she says. ''It was hard. I'm having a hard time now, because, you know, we had a great nine years together. It's just over. It's the end of an era.'' Paul Guilfoyle, who plays Captain Brass, agrees: ''I have such a fondness for Billy, but the show will go on. It has to.''

Petersen has definitely left his mark on this crime scene. From the moment in 1999 when he persuaded creator 
Anthony E. Zuiker to change Gil's last name from Sheinbaum to Grissom, to the spring of 2007 when he began to map out his character's much-anticipated exit, Petersen has played a significant role in the direction of his hit show. ''The first day I met Billy, before filming the pilot, he said to me he wanted to re-create an ensemble feel of a theater company, to have that type of collaboration,'' says executive producer Carol Mendelsohn. ''It's not the easiest road to take, to have true collaboration. There were a lot of fights, a lot of disagreements.'' Like the time Petersen insisted on showing his naked butt during Grissom's stay at a hospital in season 3. Mendelsohn objected, believing it would come off more NYPD Blue than CSI. They shot it both ways, 
 and while Mendelsohn ultimately won that battle, she feels Petersen's insistence on teamwork ''has been an essential element to our success, on every level.''

The actor even felt emboldened enough to brush off directives from the very top, as when CBS president Leslie Moonves asked him to shave the not-so-attractive beard he started sporting in the fourth season. ''I'm superstitious,'' says Moonves. ''If it ain't broke, don't fix it. Here's a leading man people love with a high Q Score. He's on the No. 1 show. Why screw around with luck? Yet he chose politely to ignore me.'' Petersen, who's unapologetic about his occasional my-way-or-the-highway antics, says he wanted a producer title to ensure that the cast and crew always had an advocate. ''Otherwise, it's completely unbalanced because everything is tilted toward the network and the studio and the writers. It can't just be generals. You have to have a few lieutenants. That's where I came in.''
