How to Train Your Dragon/Trivia

• This is the 100th animated feature film produced by DreamWorks Pictures.
  • Additionally, the 2010-2017 logo (that debuted in the film) showed the workmark "100th Animated Feature Film".
• After the Moon Boy sitting on the moon in the DreamWorks Animation logo at the begining of the film flicks the fishing line, a black shadow can be briefly seen obscuring some of the stars to the right of the moon as it flies past. This is likely Toothless, as he is the only black dragon shown in the movie.
• This is also the second movie Jonah Hill and Christopher Mintz-Plasse were in together since 2007's Superbad.
• The theatrical, DVD, Blu-ray, and television releases use the 2003 Paramount Pictures logo after the end credits, but the 4K Ultra HD Blu-ray release uses the 2013 Universal Pictures logo, so don't except to see the same version twice.
