Pursuing an acting career upon his undergraduate graduation, Harper began making a name for himself in theater and film. First playing an extra in Spike Leeâ€™s Malcolm X, the actor became a supporting actor in He Got Game (1998) and The Skulls (2000). Four years later, Harper acquired a leading role in CSI: NY as Dr. Sheldon Hawkes. He also made waves on stage, starring in Off-Broadway shows such as Our Handsome Captain, Freeman, and David Mamet's American Buffalo. He is also a member Boston's Black Folk's Theater Company. But one of the most interesting facts of all, Harper was a classmate of President Barack Obama at Harvard Law.
