Oscar-winning screenwriter Tom Schulman (“Dead Poet’s Society”) is writing an original for Joe Roth’s Caravan Pictures that will mark his feature directorial debut.Schulman was unavailable to discuss the project he is writing for the Disney-based indie company. Schulman will executive produce Caravan’s upcoming late fall production of “Tall Tale,” which Jeremiah Chechik will direct from Steven Bloom and Robert Rodat’s script. Schulman had been developing a similar project at Disney titled “Tall Tales.” Roth said it was through his new association with Schulman that the writer told him of his idea for “Holy Man,” a modern-day character comedy. “When he told us about the idea, I thought we’d be very helpful to him as producers on the project, which is his directorial debut,” said Roth. Schulman, who served as executive producer on Paramount’s current box office hit “Indecent Proposal,” also scripted Disney’s hit comedy “Honey, I Shrunk the Kids,” Touchstone’s “What About Bob?” and Cinergi/Hollywood Pictures’ “The Medicine Man.” Caravan is about to roll cameras on its first production, “The Three Musketeers” (which begins today), followed by the Geena Davis starrer “Angie, I Says” (May 24), the Julia Roberts-Nick Nolte romancer “I Love Trouble” (Oct. 3) and “Tall Tale” (early September).
