Wentworth Miller has joked that he's too old to do his own stunts.

The 44-year-old actor is reprising his role as Michael Scofield for a 'Prison Break' revival but he admits filming the action scenes is a lot harder now.

He said: "[Stunts are] a lot different at 44 then they were at 34. I do what I can, but if I need my character to look cool and like he knows what he's doing and my stunt double can execute that better, then I'm happy to step aside. It's just in service of telling the best story possible."

Wentworth was speaking at Comic-Con in San Diego and although he'd been at the event before, he admitted he doesn't remember it.

He said: "[My co-star] Dominic [Purcell] tells me that we did a Prison Break [panel] at Comic-Con when the show was originally airing. I have no recollection of that, but I just trust that he's telling me the truth.

"It's nice to be back, even though I don't remember what happened before. But it makes sense to me in a strange way that Prison Break is at Comic-Con, because it's got kind of a comic book element to it and always has, so in that way, it feels like a marriage."

'Prison Break' ran from 2005 to 2009.
