Focus Features and Blumhouse Productions’ Insidious: Chapter 3 takes a trip back in time before the events of the demons that haunted the Lambert family. Leigh Whannell makes his directorial debut replacing James Wan, who left to direct Furious 7.

Having already written and starred in the first two chapters, Whannell seemed like a natural fit to direct the third. However, in our roundtable interview the director revealed that there were some fears about coming on to a sequel that already has a deep mythology and a fanbase. He also talks about some of the difficulties of writing, directing, and acting simultaneously, the use of practical effects over CG, and meeting expectations. Hit the jump for the interview.

The first teaser trailer for Insidious: Chapter 3 has been released online by Focus Features.

The sequel is directed by Leigh Whannell, who makes his directorial debut. Whannell is the creator of the Saw franchise, writing the short that started it all plus Saw 1-3. He also wrote and starred in both previous Insidious movies.

Insidious 3 stars Dermot Mulroney, Stefanie Scott, Lin Shaye, Angus Sampson, and Whannell, and will be released on May 29, 2015.
