I once was told a story about how Michael Dorn auditioned for the role of Commander Worf on Star Trek. Instead of saying what the script he was given said, he tried to "act" like a Klingon would.
When it was his turn to audition, he put on his meanest face, stomped into the room, roared at the director, smashed the script on the table and stormed off again, unimpressed by anyone. After he left, the director then exclaimed "That's a Klingon!! I want him as Worf!"
However, I can't find any evidence about this story and whether or not it is true. I'm looking for a source to prove or disprove this story (even though the story is pretty great and fits the role of Worf).
