Joaquin Phoenix to David Letterman: I'm sorry

NEW YORK – Joaquin (wah-KEEN') Phoenix says he's sorry for a wacky appearance on David Letterman's "Late Show" that turned out to be an elaborate piece of performance art. Phoenix apologized Wednesday to Letterman for last year's visit, saying that he hoped no offense was taken. Letterman said it seemed that the bearded, mumbling Phoenix looked like he had slipped and hit his head in the tub. Letterman said he took no offense, saying: "It was so much fun. It was batting practice, you know what I mean? Every one of them was a dinger." Phoenix said last year he was giving up acting for a rap career. He actually was filling a role for filmmaker friend Casey Affleck. This week, he was clean-shaven, with trim hair and no sunglasses. — AP
