Bolaji Badejo, was initially a graphic arts student before starring in Ridley Scott's feature film, 'Alien'. His 7'2 slender stature earned him the role of playing the creature in Alien. Despite his lack of acting experience, he was able to beat Peter Mayher (the guy who played Chewbacca) and earned the role.
However, Bolaji Badejo was a Nigerian design student and never envisioned himself as a movie star, even though famous actors like Christopher Lee earned their fame through playing monsters. But Bolaji said in an interview shortly after the film's release that nobody would know that he played the creature in Alien, but the fact that HE knew was enough.
After a brief moment in the spotlight after the movie was filmed, Bolaji seemed to disappear off the face of the Earth. In fact, nobody knows if he is dead or alive - although many people on the internet claim to know him and his family in real life, and have said that he passed away.
