Based on a popular book by Vince Flynn, American Assassin sees 23-year-old Mitch Rapp (O’Brien) take action against a group of extremists who carry out a terror attack on a beach that kills his fiancee. Rapp is flagged to the CIA and subsequently enlisted by a Black Ops unit led by grizzled veteran Stan Hurley (Michael Keaton).

The film traces the steps Rapp undertakes from lone vigilante to valuable government asset.
O’Brien spoke to us about filming the opening scenes of the film, including how he worked with his dad on the initial attack sequence. We also spoke about what it was like getting stuck into the action scenes and dealing with serious topics that are currently in the news.
American Assassin is released in the UK on September 14.
