The Sony remake also stars Whitney Houston
Luke will play Stix, a songwriter who helps a Harlem-based singer break into the big time. The part was originally assayed by "Miami Vice" star Philip Michael Thomas.
Others in the cast include Whitney Houston and "American Idol" winner Jordin Sparks.
Since that time he's scored several supporting roles in a wide array of films such as "Captain America: The First Avenger," "Friday Night Lights," and "Madea Goes to Jail."
