This episode, which was written under "extreme pressure" during the show's brief Christmas hiatus, has been stylistically compared to the comedy film "Groundhog Day" (1993). Vince Gilligan and John Shiban, the writers of the episode, however, credit an episode of "The Twilight Zone" entitled "Shadow Play" (1961). Gilligan later noted: "The funny thing about 'Monday' is people seemed to really like it a lot, but people always sorta smiled and said you're sort of ripping off "Groundhog Day" aren't you? [...] And I'd say, we're not ripping off "Groundhog Day", we're ripping off "The Twilight Zone"."
