11. The Undertaker Reaches New Heights (Suburban Commando, 1991)
Suburban Commando may not be the most well-regarded sci-fi movie of the 1990s, but it does boast a very rare out-of-character appearance from The Undertaker. 'Taker and towering actor Tony Longo portrayed a pair of intergalactic bounty hunters (Hutch and Knuckles, respectively) who came to earth in order to fulfil their mission, consequences be damned. The Deadman only delivered a single line, but it was dubbed over with an Alvin and the Chipmunks-style falsetto. Thankfully for The Phenom, the high-pitched voice was quickly forgotten and he was able to remain a feared force in WWE.
