But the previous years have had their fair share of beautiful, comic and outrageous moments. So here's a look at some of the most iconic moments in Oscar history.

8) Roberto Benigni's acceptance speech: Not many Oscar winners can match the absolute joy actor Roberto Benigni expressed on winning the best actor award for Life Is Beautiful in 1999. He climbed over the seats to get to the stage and then told the audience in a heavy Italian accent, "I would like to be Jupiter and kidnap everybody and lie down in the firmament making love to everybody!"
