BURBANK — James Wan walked away from his first chance to make a sequel, for the “Saw” franchise he helped create. Now he can't seem to escape them. The director has been splitting his days this summer between pre-production on the seventh “Fast & Furious” film and putting the finishing touches on his indie scare-fest “Insidious 2,” due in September. His other haunted house movie, “The Conjuring,” has become the season's biggest low-budget hit. It's heading toward $100 million at the US box office since its release last month, more than the mega-budget “Pacific Rim” and “The Lone Ranger.” No surprise here: The tale of a New England demonic possession leaves a creaky door flung wide open for more movies starring ghost hunters Ed and Lorraine Warren, played by Patrick Wilson and Vera Farmiga. “If there's a need for more stories, then so be it. That's a good thing,” Wan said in an interview. “But I always set out to make the best film I can and let the people decide if it has a longer shelf life or not.” — AP
