FILM chiefs have rated a theme park attraction too scary for under 12s
The British Board of Film Classification moved after examining the Nemesis Sub-Terra at Alton Towers.
Until now the BBFC has only dealt with films or games, but were called in by the park before the ride went live.
Bosses at Alton Towers decided to take advice after seeing testing panel results before the opening on March 24.
Now the film board has slapped it with a 12A certificate, meaning under 12s need an adult with them to go on it.
Murray Perkins, Senior Examiner at the BBFC said: "We are seeing a real blur of the old boundaries of visual content and physical experience in both 3D and 4D cinema, and at theme parks.
"After experiencing the attraction first-hand, based on 100 years of experience and line with British public opinion, we would recommend that Alton Towers Resort classify the new Nemesis Sub-Terra a 12A.
"It contains some intense moments, in some respects comparable with scary scenes which may be experienced in horror or science fiction films."
Secrecy surrounds the new attraction, but it is set underground in a system of caves.
It is based on the back story of the original Nemesis ride, which opened in 1994.
Spokesperson Katherine Duckworth said: "The classification is important for the resort to ensure the wellbeing of our guests.
"We are aware the enforcements that will now be implemented will mean that many of our younger visitors are unable to experience Nemesis Sub-Terra, which we are obviously concerned about.
"However, the Alton Towers Resort prides itself on offering a variety of rides for all ages and we hope that those under the age of 12 will continue to enjoy our other attractions."
