Sigourney Weaver was a guest on the Graham Norton Show, and Norton decided to reenact John Hurt's famous "chestburster" moment from Alien. Comedian Sandi Toksvig has amazingly never seen Alien at all, so she was the perfect person to take John Hurt's place. Worth watching both for the huge amounts of gore, and for the look of dismay on Weaver's face.

This episode of the Graham Norton Show will be on BBC America on Saturday evening at 10 PM.
