Redditor pbbtttb links to SlashFilm's theory that in "Ferris Bueller's Day Off," Ferris doesn't exist. Instead, he's a manifestation of the more introverted Cameron's id — just like Tyler Durden, Brad Pitt's character in "Fight Club."

Is Ferris Bueller a real person?

Edward McNally was rumored as the inspiration for the character Ferris Bueller. McNally grew up on the same street as Hughes, had a best friend named "Buehler", and was relentlessly pursued by the school dean over his truancy, which amounted to 27 days absent, compared to Bueller's 9 in the film.

Is Cameron Real in Ferris Bueller's Day Off?

It may sound ridiculous but, despite being the main character in the beloved 1986 movie, some fans are certain that the cheeky chap isn't even real. According to film buffs on MetaTalk, Ferris Bueller's Day Off has a Fight Club element to it, and Ferris is just a character invented by sick, friendless Cameron.
