The trailer for the 3D animated film How to Train Your Dragon has arrived online, and it's looking rather good, despite the fact it's delivering for 3D I actually managed to get caught up in it, and the look of the dragons is rather cool.

The film stars the voices of Jay Baruchel, Gerard Butler, America Ferrera, Craig Ferguson, Jonah Hill, Christopher Mintz-Plasse, Kristen Wiig, T.J. Miller and Kieron Elliott, quite a cool line-up, especially as it features two Scotsmen!

Imagine a land where Vikings and Dragons are mortal enemies. Where the teenagers of the island of Berk are trained in how to fight and kill the Dragons. However along comes Hiccup, a strange teenager who doesn't fit with the rest of the Vikings ready to start training but is eager to begin. This is How to Train Your Dragon.

One night his invention downs a dragon, and when he races to find it and kill it, he just can't bring himself to do it. Instead he lets it go, finds it some food, nurses it back to health, and before you know it he's befriended a Dragon and they both realise that there's more than this fighting malarkey.

Here's the trailer for How to Train Your Dragon which you can see over at Yahoo Movies in high definition.
