Andrei Arlovski opens the list, and he can at least be credited with appearing in a film franchise very recognizable to fight fans, film goers, and likely, the readers: the Universal Soldier franchise. Unfortunately, after the original movie, there wasn't much good to say about the series for a while - though recent instalments have had some decent reviews, for what it's worth. Arlovski turned up in a pair of Universal Soldier movies, Regeneration and Day of Reckoning. Regeneration had Jean-Claude Van Damme back, as well as Dolph Lundgren, and The Pitbull played a Next Gen Universal Soldier. The film wound up with a cult following which led to Day of Reckoning being produced (the first in the series to be shot in 3D). Day of Reckoning didn't quite live up to Regeneration, but Arlovski returned as an NGU.
