That’s Bolaji Bodejo. I love knowing that.
Bolaji Badejo was a Nigerian visual artist and actor who became known as one of Hollywood’s most unlikely on-screen performers in the role of the Alien in Ridley Scott’s 1979 film Alien, his only film role. He died of sickle cell anemia at the age of 39.

Badejo was of Maasai descent. He was discovered in a Soho pub by a member of Scott’s casting team. He was chosen to play the part of the alien due to his towering height [and thinness] He was six-foot-10-inches tall – Wikipedia
