A politician has joined the row about the rating of the latest Batman film, saying it should have a 15 certificate.
The Dark Knight is a 12A, which means if you're 12 or younger you have to watch it with an adult, but people are worried that it's too scary for kids.
MP Keith Vaz says he won't let his 11-year-old daughter see the film because of the violence in it.
The people who rated the film have had more than 80 complaints about it, but still say the 12A certificate is fair.
Sue Clark from the British Board of Film Classification (BBFC) said the movie is based on comic books - and you don't actually see the violence.
She said: "Batman can jump off buildings and fly and The Joker is not a realistic character and bounces back with a smile on his face."

Ms Clark added that if the film had a 15 certificate, lots of younger Batman fans would have missed out.
"We would have ended up with far more complaints from people who wanted to see the film and couldn't," she said.
So far, around 4.7 million tickets for The Dark Knight have been sold in the UK .
