Ricky Gervais: It's the 'Right Thing' for Steve Carell to Leave 'The Office'

In his interview on "Piers Morgan Tonight" Thursday, Gervais says the comedy he executive produces "can survive" without its boss.

In his first interview since his controversial turn as Golden Globes host, Ricky Gervais admitted he never tried to stop Steve Carell from leaving The Office.

"I sent him an email saying I think you're doing the right thing," Gervais -- who serves as an executive producer on the NBC hit after originating the ditzy boss role in the U.K. version -- said on Piers Morgan Tonight Thursday. Read Tim Goodman's review on The Bastard Machine blog.

"As a producer, I was expected to try and stop him because he's a big part of it," continued Gervais. "[But] you know, it can survive. Whether it should or not, I don't know. I'm just an adviser and he's done an amazing job. He's done his time. It sounds like a prison sentence, doesn't it?"

The show is "bigger than I ever thought it would be," Gervais added. "It's more successful…. He's bigger than I bet he ever thought he would be, and he's done an amazing job." PHOTOS: What the stars wore to the Golden Globes.

Gervais also admitted that he'll make a cameo this season. "It was supposed to be a secret," he said. "It's just a little pop-up. I just bump into Steve Carell." VIDEO: Golden Globes' most memorable moments.

Gervais joked that he "nearly forgot how to do David Brent," the U.K. version of Michael Scott. But then he remembered: "You just act like an idiot. It's easy. It's so much fun. I've never had as much fun playing a character as David Brent. Everything he does is so desperate. He's just so desperate to be loved."
