Sylvester Stallone Working on Another Expendables Movie

Sylvester Stallone is working on another Expendables movie. He didn't drop the news in an interview. A studio didn't share the information. Stallone confirmed it himself, wholly unsolicited, on his own social media channels. The promise of a fourth film comes five years after the last Expendables movie dropped in theaters, with the franchise having already nabbed just about every action movie star imaginable already.
