Writer-director John Warren will helm Morgan Creek’s “Major League 3,” the Warner Bros.-based company’s followup to its 1989 baseball comedy hit and the 1994 sequel.The pic, expected to go before the cameras in the late summer, will be the first directing feature for Warren, who also penned the screenplay. The new story is designed to be a fresh take on the franchise. The original was about a team owner who tries to get out of her baseball franchise by setting up a losing team. The sequel will be produced by James G. Robinson, with Gary Barber and Bill Todman Jr. as executive producers. Warren wrote and directed Showtime’s upcoming “The Curse of Inferno,” and co-wrote “Naked in New York” with Daniel Algrant. He also wrote “Girl in the Cadillac.” Other projects include “Supermodel,” set up at Walt Disney Pictures, and “Tark the Shark,” set up at Showtime. In setting off to helm “Major League,” Warren already has a home field advantage. He played on a varsity team at Ohio U., where his fellow players included Mike Schmidt (who went on to the Philadelphia Phillies), Steve Swisher (who went on to the Chicago Cubs) and Bob Brenly (who played for the San Francisco Giants). Warren is repped by David Styne and Tori Metzger at CAA.
