Where can I watch The Forgotten in United States?

Based on a story by Vietnam veteran Paul Staples, the film concerns six American Green Berets, held for 17 years in a Vietnamese POW camp. They are finally released in secret, during a delicate trade-talk session between Vietnam and the United States. Captain Tom Watkins, the ex-prisoners' CO, begins to suspect that government-man Adam Roth, who is in charge of the debriefing, may be pursuing a hidden agenda that will result in the early deaths of Watkins and the five men under his command.
