Expendables 3 will star literally every actor you've ever heard of in your entire life, from Mel Gibson to Jackie Chan to Wesley Snipes. They're all joining either Stallone's hardcore crew of mature student mercs or the sexy bunch of young turks who will oppose them. All except for Bruce Willis.
He had a brief cameo in the first movie as Church, a shady character who sets up the jobs for Sly and his crew, and a much bigger role in the sequel where he got to drive round in a golf cart with Arnie shooting people and doing quips. Yet Stallone himself tweeted today that Bruce would not be returning for a 3rd bite of the apple with a grenade hidden in it.
