My 9 year old stepson loves (as in begs to watch on loop) a film called Battleship. I'll be honest, I think it's a pile of poop, but all his friends feel the same about it, so there must be something I'm simply not getting.
It is classified 12A and my inner feminist cries a bit when I watch it, but other than that nothing horrific.
He does also love Warhorse, the Narnia films and The Golden Compass, but these have all been out a bit longer. We took him to the cinema to see Skyfall and he enjoyed that, again I think that is a 12A.
