Was discovered in a bar by a member of the film crew of Alien - O 8º Passageiro (1979), who felt that he would be ideal to play the title creature, as director Ridley Scott wanted to create a monster that looked as if no human could be behind the mask. It was to be long and angular, with an impossible frame that few people would be able to fill. Even though he had no training or experience as an actor, Badejo's 6-foot, 10-inch frame and thin build made him ideal for the part.
