A horror film which has left audiences in the US feeling sick is due to open in the UK tomorrow.

Cloverfield features strobe lighting effects, shaky footage and flashing lights which cause sickness, nausea and dizziness in viewers.

The thriller is told from the point of view of five young New Yorkers using their handheld camera.

Paramount, the distributor, has advised cinemas to issue a health warning before screening the film, saying ‘it may cause adverse reactions’.

James Christopher, a reporter from The Times, said after seeing the film: “I couldn’t look at the stroboscopic effects in the final reel, and nearly threw up trying to make sense of the climax.”

A blogger on the popular movie database IMDB.com said: “I had to get up and leave the theater for nearly 20 minutes just to keep from hurling.”

In the US, cinemas posted signs warning moviegoers of potential “side effects associated with motion sickness similar to riding a roller-coaster.”

Those wishing to watch the reality-TV thriller have been advised to take a dose of over-the-counter anti-vertigo medicine, to briefly close their eyes during the film – or just to wait until it comes out on DVD.

“A person would be fine watching from home,” said Dr. Michael G. Stewart, chairman of otorhinolaryngology at NewYork-Presbyterian Hospital/Weil Cornell Medical Center.

“When you are on your couch, you have perspective around the screen so your mind knows the movie is moving and the room isn’t.”
