Children today are more frightened of movie villains like Lord Voldemort in the Harry Potter film than traditional baddies, a report has shown.
In the old days, scientists reckon kids were more scared of the 'bogeyman' or the pretend 'monster under the bed'.
They think movie baddies are worse now because modern special effects make villains look so realistic and terrifying.
Two thirds of all children under 10 are also scared of the dark, the study showed.
The Lord of the Rings, which was given a PG rating, has a special warning attached to it saying it may not be suitable for under eights because some scenes are too scary and violent.
