Arnie must have gone straight back into acting as soon as he finished governing, if the current crop of films are anything to go by. First there's the Expendables 2, which has just come out over here, and now he's also in The Last Stand with Johnny Knoxville (who seems to be playing himself).
By the looks of it, it's a pretty standard Arnie actioner, with him playing an old sheriff in a small American outback town who's forced to defend it when convicts/thieves/terrorists try to drive through in an armoured snowplough. Although if there's any more to it than that, we'll be disappointed.
Anyway, have a look, see what you think...
