Here's Jelveh:
The average profit margin for the top 45 grossing franchises of all time (where Saw is #44) is 605%. Saw's average margin is three times higher at 1,804%. (The next closest are Home Alone (1,365%), Jaws (1,341%), Star Wars (1,055%), and Lord of the Rings (986%).)Amazing. Tragic.
Given it's insanely cheap budget, you'd think that the rickety Blair Witch Project movies could have made a run for Saw's money, but Blair Witch 2 stupidly changed the aesthetic to look more professional and flopped. It was like going to see Finding Nemo 2 and getting live-action footage of Shark Week.
