Oscar year: 2007
His Norbit: Norbit. Murphy is the origin of this pop-culture euphemism for a lightweight popcorn flick that is released in the throes of awards season when the timing can be awkward at best and Oscar poison at worst.
How it went down: Murphy was the Best Supporting Actor front-runner for Dreamgirls. He won the Golden Globe and the SAG award, but then came ads for the how-low-can-you-go-brow Norbit.
Did it hurt him? Yes. Murphy lost the Oscar to Little Miss Sunshine's Alan Arkin.
