Who do you call when you need to revive a popular action franchise like The Expendables after nearly a decade-long hiatus? Probably a stunt performer. Enter Scott Waugh, Expendables 4 director and a former stuntman who was "born and raised on set"--his late father, Fred, was a movie and TV stuntman going all the way back to the 1960s, and both Scott and his brother, Ric, are stuntmen-turned-directors.

"Being an ex-stuntman always gives me a little bit of a leg up coming into a set," Waugh said. "So to come in with these action heroes, I don't want to say I'm on common ground with them, but there is a commonality between us."

Warning: This article describes a particularly cool action sequence from late in the film.
