PICS: Candid Celeb Sightings
"A lot of it is Barbara [Hershey's] character and I trying to solve what's happening with Josh," Sampson explained.
In Insidious: Chapter 2, the Lambert family's story picks up after Josh's [played by Patrick Wilson] possession, leaving the characters in search of answers.
Despite the movie's dark subject matter, Whanell described shooting the film as a sort of family reunion.
"We put the band back together!" said Whanell.
Barbara Hershey, Rose Byrne, Lin Shaye and Patrick Wilson all return for the second installment, out September 13.
