It looks like filmmaker Clint Eastwood has a new project on the horizon. The director is set to make a true-life tale of American tourists who thwarted a terrorist attack. The movie is based off the book: 'The 15:17 To Paris: The True Story Of A Terrorist, A Train, And Three American Heroes'. Although no announcements have been made concerning casting for the film, whoever signs onto the project will be expected to work hard. In a recent interview, actor Tom Hanks opened up about his experience on set with Eastwood for the film "Sully". Hanks said that Eastwood works his actors "like horses."
