The Expendables 4 is bringing the action hero ensemble franchise back to theaters, but one new crew member of The Expendables 3 may not be returning for the team's next ride. The Expendables first took off in 2010, with Sylvester Stallone leading a crew of action movie veterans in a throwback to '80s and '90s action films. The Expendables franchise hit its first snag with 2014's The Expendables 3, which underperformed its two predecessors due to its ill-advised PG-13 rating.
