Its hard to believe, but Bill Murray is 60 years old today. In 1976, he joined the cast of Saturday Night Live for the show's second season. After starring in Meatballs in 1979, Murray went on to star in a series of successful comedies in the 80s, including Caddyshack, Stripes, and Ghostbusters. He then went on to reinvent himself with his starring role in Rushmore in 1998, re-reinvent himself again with his starring role in Lost in Translation in 2003, kick ass in Jim Jarmusch films, accidentally star in Garfield, chill in his mansion in the middle of the zombie apocalypse in Zombieland, and hilariously passive-aggressively trash Ghostbusters 3 every chance he gets nowadays. In short, he is still a giant of comedy and a monument to reinvented relevance, and for this, we salute him. Here are some interesting Bill Murray facts:* Bill Murray had originally planned a career as a doctor, although he left university after being arrested for possession of marijuana. Truly, medicine's loss was ruefully existential arthouse cinema's gain.* Bill Murray is notoriously hard to pin down. If you want him to star in your film, you have to call his infrequently checked answering machine and wait for him to get back.* As a consequence of this, he has missed out on roles in films like Monsters Inc, Charlie And The Chocolate Factory and Who Framed Roger Rabbit.* Bill Murray was the singer in a band called the Dutch Masters as a teenager. What's more, he once played guitar onstage with Eric Clapton.* Bill Murray's final inaudible whisper to Scarlett Johansson at the end of Lost In Translation is one of cinema's greatest-ever mysteries. In 2007, a digital remaster discovered that he appeared to say, "I have to be leaving, but I won't let that come between us, OK?"* It's said that Bill Murray likes to sneak up behind strangers in New York, whisper, "Guess who?" And, when they turn around, tell them: "No one will ever believe you."Happy 60th Birthday, Bill!
