This one goes out to my brother. Here is the entirety of an IMDB news item entitled "Jackson's snake film creates huge buzz":
"Samuel L. Jackson's new mile-high thriller "Snakes on a Plane" has created such a buzz among internet film fans, movie bosses have called for re-shoots - to give the film a tougher rating. The film, which stars Jackson as an FBI agent trying to keep a federal witness alive onboard a plane full of snakes, wrapped last September - but went back before the cameras earlier this month for five days of additional shooting. Film bosses at distributor New Line Cinema opted to add new scenes to the film to take the movie from PG-13 into R-rated territory, according to industry magazine The Hollywood Reporter. They claim the second round of filming became necessary after intense and growing fan interest in the film, which is scheduled to be released this summer. Among the reported additions to the film is a foul-mouthed rant from Jackson in which his agent character bellows, "I want these motherf**king snakes off the motherf**king plane!" The line is expected to take on cult status. The film-makers have reportedly added more gore, more deaths, more nudity and more snakes to the finished product."
