Snakes on a Plane went back to reshoots in response to an enthused internet response. They toughened up the film to an "R" rating to appease the online fan base. I think this is a mistake. Clueless executives greenlighting a film in which Samuel L. Jackson shouts "I want these motherfucking snakes off the motherfucking plane!" can produce a cult classic; when marketing flacks insert the quote "I want these motherfucking snakes off the motherfucking plane!" because their scouring the internet reveal that that's what fans want to hear, just sounds pathetic.
