EXCLUSIVE: Jon Turteltaub could soon be swimming with a shark, a great big historic toothy critter. He’s now circling Meg, an adaptation of the novel that Warner Bros is moving forward with in conjunction with China-based Gravity, with Lorenzo di Bonaventura producing. This is a film 20 years in the making, and Turteltaub enters the picture after Eli Roth quietly exited. He came attached last year. The script is by Dean Georgaris, and Belle Avery and Colin Wilson are also producers. Gravity will release the film in China. Pics about an attempt to kill a giant shark decimating swimmers along the China coast. They figure out it’s Megaladon, considered one of the largest and most powerful predators in history, can reach a maximum length of 60 feet. The book was first attempted by Disney back in 1997 and it has reared up numerous times since, but it looks like this time’s the charm. Given the success of Jurassic World, it seems a good time to take a bite out of the global shark market. Turteltaub, repped by WME and Oasis, last helmed Last Vegas.
