Alec Baldwin hasn’t hosted the Oscars before, but he’s hosted Saturday Night Live 14 times, which is about as good as hosting an Oscar ceremony. Beyond his lengthy film career, he’s probably best known for “30 Rock” and letting his less-famous brothers crash next year’s Oscars. source
Steve Martin has already hosted the Oscars twice, in 2001 and 2003. The jack of all trades (he has an Emmy, two Grammys and a doctorate) has successful writing, music (he’s an awesome banjo player), acting and comedy careers under his belt. Plus, he can juggle. Can you, jerk? source
