Update: a new trailer of How to train your dragon has shown up:

Plot:
“A comedy adventure set in the mythical world of burly Vikings and wild dragons.”

Voice Cast:
– Jay Baruchel as Hiccup Horrendous Haddock the Third – The main character of the film and son of chief Stoick the Vast. According to his cousin Snotlout, he is nothing like his father, is not suited to be the future chief, and is wimpy. Hiccup finds and befriends an injured dragon named Toothless, bringing into conflict his new friendship and the village’s tradition of dragon-fighting.

– Gerard Butler as Stoick the Vast – The short-tempered chief of the Hairy Hooligan tribe. He hopes his son will mature up and become strong enough to be chief one day, but it does not seem to go well for him.

-Christopher Mintz-Plasse as Fishlegs – Fishlegs is Hiccup’s best friend who does not seem to be good at any of the subjects that the teachers in the Viking training program teach. Fishlegs is nervous and frightened to do perilous things at times, but remains Hiccup’s best friend. He owns a dragon named Horrorcow.

– Jonah Hill as Snotface Snotlout – The son of Hiccup’s uncle, making him and Hiccup cousins. Snotlout hopes to be the chief one day, but Hiccup is the heir (in fact, if something happened to Hiccup, he’d be next in line for the job), which has spawned a hatred between them. He is strong and muscular, and is good at being a Viking. Snotlout owns a dragon named Fireworm.

– America Ferrera as Astrid.

– Craig Ferguson as Gobber the Belch, the head teacher in charge of the Viking Initiation Program. He’s loud, short-tempered, and finds everyone in his program pathetic.

Looks like we will have thrilling 3D rides on flying dragons in the Dreamworks movie How To Train your Dragon!
