Johnny Depp appeared on The Late Show with David Letterman last night and was wearing a very interesting outfit that was part old west and part homeless vagabond. While on the show to promote his latest film The Tourist, the 47-year old also dished on what it was like working with Al Pacino…

The 47-year-old actor said, “Al’s fantastic, I mean Al’s a legend. He’s Al Pacino. He’s an amazing actor. The one thing I didn’t really know about Pacino prior to shooting was that he’s certifiably insane.”

“He’s a joker, he likes to tell jokes and he liked to tell me this one specific joke over and over and I really didn’t understand it. I didn’t get the joke. He definitely thought it was my problem. He inflicted it upon me,” Depp added.

Depp also said that his two children, Lily Rose and Jack, with his long-term partner Vanessa Paradis are basically nomads at the moment, “Spending time in France, Los Angeles and then wherever the location is.”

That maybe explains the ‘living out of a cardboard box’ fashion a bit more.
