In Ridley Scott's classic 1979 science fiction/horror film Alien, the terrifying creature was played by a 6'10" Nigerian named Bolaiji Badejo. It was Badejo's only film credit. In fact Badejo, who died of sickle cell disease in 1992 at age 39, wasn't even an actor. He was studying graphic arts in London when casting agent Peter Ardram spotted him in a pub. From CNN:
"As soon as I walked in Ridley Scott knew he'd found the right person," Badejo said in a rare interview for the French film magazine, Cinefantastique, in 1979…
"I could barely see what was going on around me," Badejo recalled in 1979, "except when I was in a stationary position, while they were filming. Then there were a few holes I could look through… It was terribly hot… I could only have it on for about 15 or 20 minutes at a time. When I took it off, my head would be soaked."
