Dreamworks Animation’s How To Train Your Dragon is due to his cinemas on March 31st, and to help build the hype, a new viral featurette has been released, featuring a Viking teaching us, well, how to a train a dragon. Apparently there are various species and so you need to know what to do. The film itself tells the story of young Hiccup Horrendous Haddock III, who isn’t particularly keen on the whole dragon-killing culture of his clan, and after failing to slay one of the mighty beasts, ends up taming and befriending it, which turns his whole world upside-down (click here for the trailer).
