Director Takashi Shimizu went to Los Angeles to meet with producers Rob Tapert and Sam Raimi in a small office at Columbia Pictures. The purpose was to develop a story outline for the sequel's first draft, which also involved employees from Tapert and Raimi's production company Ghost House Pictures, producer Taka Ichise, and writer Stephen Susco. According to Tapert, the session was roughly seven or eight hours of people suggesting ideas for the story.
To keep the mood on the set light, the actors and director would often joke around and attempt to frighten one another. This included a Karaoke session performed by Shimizu, Takashi on Kebbel, Arielle's birthday.
