Landham's bodyguard
It wasn't just the Predator who the soldiers had to fear!
Sonny Landham, who portrayed the squad's hacker Billy, was infamous for being short-tempered, and so the studio hired a bodyguard to protect the cast from his explosive outbursts.
Director John McTiernan said: "We had this 6-foot 8-inch tall giant who had to follow Sonny around 24 hours a day the entire time he worked on the movie and make sure that he never misbehaved.”
