Assuming we're not including people who have only been in WWE Studios movies, JoMo.
Jerry Lawler starred in that one cheesy thriller/horror movie Girls Gone Dead.
Kevin Nash was also in The Punisher and Magic Mike. I'm refusing to include The Longest Yard just because part of its gimmick was having a bunch of wrestlers. Which is the same reason I'm not counting Ready to Rumble or The Wrestler.
Triple H was in Blade Trinity.
Nathan Jones was in a few movies. Mad Max: Fury Road being the most recent I can think of.
Jericho in MacGruber(also starring smaller parts from Mark Henry, Khali, MVP, Kane, and Big Show).
Andre in The Princess Bride.
There's also that goofy ass Kaiju movie where Kota Ibushi and Minoru Suzuki turn into giant versions of their selves and battle.
