After teasing the sequel earlier this year, DreamWorks today released the first official full-length trailer for How to Train Your Dragon 2. The movie will hit theaters on June 20th next summer.

The movie is the sequel to the 2010 hit animated film How to Train Your Dragon. That 3D movie became one of DreamWorks’ most acclaimed movies and the animation studio is now determined to turn what was an adaptation of children’s books into a full movie franchise. A third How to Train Your Dragon Movie has already been announced and will be coming to theaters during the summer of 2016.

For How to Train Your Dragon 2, Jay Baruchel is back as the voice of Hiccup, the young viking who plays by his own rules and is the son of viking chief Stoick, voiced by Gerard Butler. Jonah Hill, Craig Ferguson, Cate Blanchett, and Kristen Wiig have also leant their voices to the production.

The sequel will show Hiccup and his dragon, Toothless, discovering an ice cave that harbors even more dragons – and a secret that is blatantly spoiled at around the 1:25 mark:
