Los Angeles, Sep 25 : Hollywood star Michael Caine says he was familiar with "every mafia guy in Las Vegas" at the height of his fame and he tells how. The star, who turned 90 in March and who famously portrayed a London gangster in 'Get Carter', said he got close to mobsters after taking a trip to Sin City with Frank Sinatra, reports aceshowbiz.com. "I'll tell you who liked a laugh - Frank Sinatra. He was very nice, he became my friend, and he loved to laugh. But he never did many things that made you laugh. He was very tough. He took me to Las Vegas on his private plane, and then I knew every mafia guy in Las Vegas. I had dinner with them all," he told the Daily Telegraph. Caine first met Sinatra when the actor went to Hollywood in the mid-1960s, where he said he was amazed to be mixing with stars he idolised. He said, "It was the most incredible experience." "It was like living with gods. I'd go out to a restaurant and there'd be John Wayne sitting there, all sorts of people - and they'd all say hello. They treated me as one of them! I lived there, I worked there, I occasionally won an Academy Award and all that. I was just like them." Caine said that his mortality is on his mind as he knows how he wants to go down in history. He said when asked how he would like to be remembered, "Let me see? For the fact that I remained an actor all my life, and I never went into anything else. I never left, I never wanted to leave." /IANS
