The No Country for Old Men star admits he got too wrapped up in the idea that the character he was trying out for was half man-half fly.
He tells Men's Journal magazine he fell to the ground and started spitting all over the room, prompting his agent to call him immediately after the try-out.
He recalls, "He said, 'What did you do?' I said, 'What do you mean, what did I do? In the part, the guy's coming out of a cocoon. He's transmogrifying.'
"(My agent said), 'Well, they were really afraid. I mean, they were scared.'"
The role eventually went to Eric Stoltz.
