We have a trailer for Harry Potter and the Half-Blood Prince. Daniel Radcliffe, Rupert Grint and Emma Watson are all back for the latest installment. Take a look inside for the trailer.

I haven't seen any of the Harry Potter films, but this looks quite dark for a film watched by a lot of kids.

The trailer for Harry Potter and the Half-Blood Prince is over on Moviefone through Jo Blo. If you live outside the US then you will need to use the HD links to see it. We'll try and get an embeddable version for you later.

Having never read any of the books or seen any of the films, it doesn't really move me either way. What about you Harry Potter fans out there, excited?

Richard: I've never read the book either, but on it's own this trailer works well. There's promise of a return of the main villain, looking as scary as ever, there's a lot of darkness, and we're getting to see Dumbledore getting in a big fight. Throw in a splash of the effects and it all looks good, but there's a strong story there too, we're going back to see how Voldemort began and what makes him tick, hopefully giving him a much stronger and dramatic on screen presence for the next film, not that he isn't already. Then there's that shot of Ron on the floor and Dumbledore and the ring, both of which seem to whisper of something more.

I think I need to wake up my resident Potter fan to watch it...in the meantime, here's the flash version:
