How to Train Your Dragon 2 (2014)
2 questions
Directed by: Dean DeBlois
Starring: Cate Blanchett, Gerard Butler, Jonah Hill, Kristen Wiig, Jay Baruchel, Kit Harington, Craig Ferguson
Continuity mistake: When Hiccup has blasted Drago off his Alpha, he looks at the tail rising and sighs "Not again." If you look closely, his sword Inferno is both in his left hand and on his hip.
Chosen answer: That's kind of left in the middle, so that Hiccup can have his revenge without having to flat-out murder someone.
