3. Cuba Gooding, Jr.
In the mid-90's, this guy was on top of the world following his breakout performance in Boyz n the Hood, a supporting role in A Few Good Men, and then an award-winning performance as Rod in Jerry Maguire. If you thought Adrien Brody was hit badly by the "Oscar Curse", he's got nothing on Cuba; following another supporting performance in As Good as It Gets, he has consistently churned out average performances in terrible movies of which there are literally too many to list here, but here is a few: Boat Trip, Daddy Day Camp and Norbit. For a guy that was riding on such a high which culminated with Jerry Maguire, I have no idea what went so wrong that he ended up being a lesser Eddie Murphy.
