It's The Expendables 2, isn't it?
Bigger role than in the first one, but still likely to be second fiddle to the rest of the cast.
Yes, kind of. I've always found him mostly watchable, like Bruce Willis, even if the films are hardly cerebral.
Hard to see him being able to fit into the current action mould though, with films like Skyfall or the comic heroes genre (we all remember his last foray there).
