Horror is a tried and true genre in the film world, known for being capable of making huge profits on a relatively small budget. That’s partly why there are so many long-running horror franchises, and why the best horror movies eventually return with new sequels. James Wan’s Insidious is in that category, as the fifth movie The Red Door recently arrived in theaters (see the Insidious movies ranked here). And franchise sar Lin Shaye recently spoke with CinemaBlend about when she realized the first movie was going to be a hit. And it’s a pretty fun story.
