Based on the Stephen Hunter novel ("Point of Impact") and the 2007 Mark Wahlberg film, "Shooter" stars Ryan Phillippe as Bob Lee Swagger, a highly decorated ex-Marine sniper who is coaxed back into action after he learns about a plot to kill the president. From the looks of things, he may have wanted to better scrutinize the assignment. Omar Epps (House) co-stars, while Wahlberg is among the executive producers.
