1. The original working title of the film was Coma Guy, which was a reference to its screenwriters, with Frederic Lebow telling Buzzfeed UK, "For a year or two, Dan [Sullivan] and I were known in LA as the 'Coma Guys.'"

2. Lebow also revealed the film's plot was inspired by a joke he once made about his own love life, explaining, "I remember at the time Dan was married, and I was having trouble getting a date. I said something like, 'I'm such a loser, I couldn't even get a date with a woman in a coma'. Dan started laughing, and we started picking at that idea."

3. The original version had the woman in a coma with the man pretending to be engaged to her.
