FILM 1434: THE GUEST
TRIVIA: The day Dan Stevens was cast, he was assigned personal trainers and dietitians to begin his physical transformation for the role. He worked out daily for 2 hours a day, even during shooting eventually putting on 25 pounds of muscle and building six pack abs for his shirtless scene.
When David and Anna are at the Halloween party a guest can be seen wearing the Fox mask worn by one of the home invaders in Adam Wingard and Simon Barret's previous feature: You're Next. The party guest is played by Steve Moore, who composed the score for the film.
The film is intentionally structured as a horror film with the pace of a thriller.
Steve Moore, who composed the score for the movie, used the same type of synthesizers that John Carpenter and Alan Howarth used for composing the score of Halloween 3: Season of the Witch (1982).
