New Samuel L Jackson film Snakes On A Plane became terrifyingly real for Arizona cinema-goers when pranksters released two live rattlesnakes into the theatre, causing widespread panic. The two young venomous diamondback rattlers were released during a screening in Phoenix on Friday. Local news reports say the snakes caused chaos among the audience and snake wranglers were called in to collect them. No one was injured during the incident and the culprits have not been caught. Officials believe the snakes were smuggled into the theatre in backpacks. According to Phoenix Herpetological Society spokesman Daniel Marchand, "All they've got to do is startle this thing. It's dark. They can't see you that well. If it's scared - boom - it strikes!" The snakes were eventually captured and released into the Arizona desert.
