Trivia: "Before I Fall" shares some pretty interesting parallels to the movie "Happy Death Day." Both films feature a young woman who is trapped in a time loop. Both films were released in 2017. Universal Pictures handled the home-video distribution of "Before I Fall" and the theatrical distribution of "Happy Death Day." And Halston Sage and Logan Miller both co-starred in "Before I Fall," in addition to "Scout's Guide to the Zombie Apocalypse," which had the same director as "Happy Death Day."

Trivia: Sam Rockwell did ride-alongs with a Los Angeles police officer to prepare for his role. He also shadowed a police officer in Missouri, on whom he based his accent and some of his dialogue, as director Martin McDonagh didn't want Rockwell to use a strong Ozark accent.
Trivia: Shawn says at one point "Jules would never do a Hallmark movie." Maggie Lawson starred in a Hallmark movie called "My Favourite Wedding" the same year this was released.
