Johnny Depp dressed up for the premiere of The Rum Diary at the Los Angeles County Museum of Art last night. He joined costars Amber Heard, Aaron Eckhart, and Giovanni Ribisi on the red carpet and later at the Chateau Marmont afterparty. Johnny spoke about the movie, which opens in the US two weeks from today, and how it was the brainchild of his friendship with the late author Hunter S. Thompson. Johnny said of The Rum Diary, "It started out as sort of a dream project for Hunter Thompson and myself — it's something Hunter suggested we do, so we started on that road many years ago. When I lost my partner Hunter in 2005, I got refueled and said, 'You know I've got to do this for Hunter, I got to make this happen.' I dove in as deep as I could, followed through, that's what it's all about — we're all here for Hunter." The evening was Johnny's second at the Chateau this week, as he also attended an art opening with friends Jordi Molla and Mr. Brainwash a couple days ago.
