A movie screening at a UK theater went from comedy to horror in less than two minutes. (but it's still pretty funny)

Parents and children at the Cineworld theater in Nottingham, England only thought they were going to see the popular children's film "Madagascar 3." Instead, they were shown the supernatural horror flick "Paranormal Activity 4," much to the terrified surprise of both children and adults.

Shocked families at Nottingham's Cineworld had to rush their children out of the auditorium as they realized that the wrong film was being projected.

But not before a scene at the very start of the film - featuring a bloodied female corpse being thrown at the camera – upset children as young as five, among around 25 families watching.

Natasha Lewis of Bulwell in Nottingham, who took her eight-year-old son Dylan to the screening, said: “They started playing the movie and I thought - this doesn't look right. And then I recognized the opening sequence as a flash back to the first movie, which I saw a couple of years ago.

“It opens on the most terrifying scene in the first film - where a body shoots full pelt towards the camera. It's enough to make grown men jump, so you can imagine the terror in these young faces.

“Everybody just scrambled for the exits, all you could hear were children crying and screaming. Everyone was very upset.

I know I really shouldn't, but I can't help laughing at this. Did nobody in that theater realize this was the wrong film until they saw a bloody corpse fly across the screen? I would think that the pre-movie trailers would give you a hint that this is no kid's flick.

I guarantee you some kids are going to be traumatized for a while because of this. And it wouldn't surprise me if some parents tried to get some money out of the theater to pay for any "psychological damage" their kids may have gotten from this snafu.
