Web TV: Prison Break's T-Bag reveals which classic character he wants to bring back

Prison Break's big comeback season has brought back a whole host of beloved characters. It's even killed off a few of them.

But star Robert Knepper – who plays fan favourite bad guy Theodore 'T-Bag' Bagwell – told Digital Spy that he's eager to bring one more classic character back from the dead.

"I miss Wade Williams [who played Brad Bellick]," he said. "They'd have to figure another way to make sure he didn't die. That wasn't in this story so far, but we'll see."

Bellick started out as a villain on the show – a horror of a prison guard who made the lives of Michael Scofield (Wentworth Miller) and his fellow inmates hell.

But slowly, he found redemption and ended up sacrificing his life to save Michael and the others – drowning as an underground tunnel flooded.

One character who definitely won't be returning to Prison Break is Alexander Mahone, another villain turned anti-hero played by William Fichtner.

"I really trust [series creator] Paul Scheuring – and Paul loves Bill Fichtner and I love Bill Fichtner," Knepper said last year. "He's a brilliant actor – but Paul honestly said to me, 'I don't know what to do with that character'.

"He didn't want to just bring everybody back, so that the audience go, 'Oh, look, it's Bill Fichtner again!' – he honestly thought, 'I'm not sure where to do that in the plot'."So if someday there's another chapter of this, maybe then Bill will be back. But I think the characters that are there, each of our moments that we have, are key to the storytelling, which is how it should be."
