“Birdman” aside, if you’re going to see an Alejandro González Iñárritu-directed film, you’re in for a long one. That’s expected to remain the case with “Digger,” the Tom Cruise-led dark comedy opening this Fall that appears to be the filmmaker’s longest film to date. The account adds that the long runtime fits with reports they have heard out of test screenings. However, Warner Bros. Pictures has NOT officially confirmed the film’s runtime at present. A new trailer for the film is tipped to be attached to copies of “The End of Oak Street” when that film opens in cinemas next Friday.
