We pretty much gave up New Line Cinema for dead, or at least moribund, after it was absorbed into Warner Bros. earlier this year, but a flurry of deals this week indicate there’s still life in the old indie label. The latest is news that Mandate pictures has commissioned a script for a third Harold and Kumar comedy that will be distributed by Warners for New Line. Yesterday we heard that John Waters had been signed to write a script for a sequel to the hit musical “Hairspray.” The label is also reportely moving along with two-sci projects: D.J. Caruso’s “Y: The Last Man,” with Shia LaBeouf attached, and Len Wiseman’s “Gears of War,” in partnership with Legendary Pictures.
