The movie sees Tom Cruise take on the eponymous action hero from Lee Child's series of novels. Paramount Pictures unveiled the first official trailer to mark Cruise's 50th birthday.
Based on Child's One Shot, the film was retitled to simply Jack Reacher in late May.
The story follows an ex-Army officer who becomes entangled in a mystery connected to the arrest of a sniper accused of killing five people.
Cruise recently split from Katie Holmes, his wife of five years.
The two reportedly clashed over Cruise's ties to the Church of Scientology.
