An Act of War (original title: The Projectionist) is a 2015 American thriller film written and directed by Ryan M. Kennedy and produced by Atit Shah.

Ryan M. Kennedy directed the film from a script he spent two years developing while working full-time as a waiter at a Midtown Manhattan restaurant.

He showed the finished draft to a French cinematographer Nicolas Canton living in New York City and the two began planning to produce the film with a small sum of their own money.

After receiving a copy of the script in January 2011, a local producer, Atit Shah offered to partner with Kennedy and the two began to work on expanding the scope of the project.

[4] Principal photography took place in March 2011, in New York City, predominantly in Brooklyn's Vinegar Hill and East Williamsburg neighborhoods.
