2. Rey Mysterio Played Freddy Krueger - Freddy Vs Jason (2003)
Rey Mysterio might not have the usual size associated with actors playing movie monsters, but he has one of the very most famous on his CV all the same.
Somewhat incredibly, Mysterio ended up playing horror movie icon Freddy Kruger for 2003's Freddy Vs Jason, following in the footsteps of his uncle Rey Mysterio, who played killer luchador El Mascarado in Wrestlemaniac.
You won't have seen his face as Freddy, obviously (very on-brand, that) because he was hired to play Robert Englund's stunt double in the boiler room dream sequence. Despite him and Englund looking NOTHING alike.
