Last week, we got our first official look at Jack Reacher: Never Go Back with the first photos featuring stars Tom Cruise and Cobie Smulders. With the October 21 release date looming, it was believed that the first trailer would arrive sooner rather than later. Sure enough, today we have the first trailer, which even includes some commentary from Cobie Smulders herself.

Cobie Smulders appeared on Entertainment Tonight last night to debut the trailer, and also provide some insight into the story. The plot follows an Army major named Susan Turner (Cobie Smulders), who took over as a Military Police commander after Jack Reacher walked away from the armed forces. After Susan is accused of espionage, Jack springs back into action to help her, while dealing with his own personal issues.

Cobie Smulders reveals that "all hell breaks loose" after Jack Reacher teams up with Susan, and that they're on the run for the duration of the movie. The new film is based on author Lee Child's 18th book in the bestselling Jack Reacher series, Never Go Back. The original movie Jack Reacher earned $80 million domestic and $218.3 million worldwide during its theatrical release in 2013.
