Steve McQueen may be gone, but he’s still influencing the film biz. Warner Bros. and producer David Heyman have set Paul Scheuring to script “Yucatan,” a heist film to be based on almost 1,700 pages of recently discovered notes and storyboards done by McQueen for a project he hoped to topline. Scheuring, creator and exec producer of the upcoming Fox drama series “Prison Break,” has already begun writing a drama about a group of thieves who head to Mexico to find a treasure buried for centuries beneath the Yucatan peninsula. The film will be exec produced by McQueen’s son Chad and godson Lance Sloane. The duo got the project started when they discovered in McQueen’s vault a couple of old trunks that contained 16 custom-made leather-bound books holding meticulous storyboards and notes.
