For those who can't watch the clip in their current surroundings, or who may not believe what they've just witnessed, here's a quick recap:

The movie makes its debut in May at the GI Film Festival in the Washington, D.C., area. The trailer's official premiere came Monday at the Indie Lounge in Park City, Utah, which runs during the Sundance Film Festival.

Much of the film's budget came from a crowdfunding effort that's still offering prizes and other perks for those interested in being a part of the film's production. Screenings are planned near several military installations, producers said, but a full distribution deal has not been announced.
