What is Casting Couch? It’s a column that has a lot of new casting news today, so settle in. Even after only two movies, the number of aged action stars who have yet to appear in Sylvester Stallone’s Expendables series has dwindled down to a select few. So, given his age, his lengthy resume, and the way he’s linked almost exclusively to the action genre, Jackie Chan has to be seen as one of the biggest fish out there that Stallone has yet to catch. It looks like that’s going to change in The Expendables 3, however, as Chan has told Cinema Online [via Coming Soon] that Stallone has invited him to join the cast of the film, and he has agreed to appear as long as it’s in a featured part and not just a cameo. Looks like we might finally get our chance to see Dolph Lundgren get beat up with a ladder.
