Before Mayhem made into the big leagues with his landmark role as Chewbacca, that he landed because his height — his feet are what got him into films when he was chosen to play a minotaur in Sinbad and the Eye of the Tiger when a feature story on people with big feet caught the movie producer’s interest.

Lucasfilms
David Prowse, who towers at 6-feet 5-inches and eventually ended up playing the role of Darth Vader, was originally supposed to be Chewbacca.
According to Prowse, it was his choice to turn down Vader because “people remember villains longer than heroes” under the assumption that Vader wouldn’t have a mask and that James Earl Jones wouldn’t be coming in to replace the audio — two features that are actually integral to Vader being Vader.
