While the movie looks to be staying largely true to its source material, Nick Frost reveals How to Train Your Dragon will feature one significant change for Gobber. Played by Craig Ferguson in the original animated franchise, the Cornetto Trilogy star is playing the blacksmith of the Viking village who is also the teacher of those looking to join the dragon hunters of the tribe. Alongside Frost, the live-action How to Train Your Dragon cast includes Mason Thames, Nico Parker, Julian Dennison, Gabriel Howell, Bronwyn James, Harry Trevaldwyn and Gerard Butler reprising his role.
