Meet D.J. Cortona. A co-star of "Detroit 1-8-7," the actor was also seen opposite Channing Tatum in "Dear John" as a character called "Noodles." In a cast of recognizable faces, Cortona's one of the few that are largely unknown. Will "Retaliation" be his break-out role? Or will he be overshadowed by performers in showier roles? (Flint was always a pretty flat, by-the-book character).
