"I apologize, I hope I didn't offend you in any way," Joaquin Phoenix tells David Letterman.
The Oscar®-nominated actor caused a stir when he came on the show wearing sunglasses and with his face covered by a big, bushy beard. He seemed totally out of it.
"Joaquin, I'm sorry you couldn't be here tonight," cracked Letterman.
Now, Phoenix admits it was all an act, part of a mock documentary he was making with Casey Affleck called I'm Still Here.
Letterman was good humored about the hoax, but dead-panned that he now expects to be paid.
"Well now you owe me a million bucks!" he said.
