The movie marks the first live-action version of DreamWorks Animation's hit series. Dean DeBlois, who directed all three animated movies, returned for the live-action version. He was hesitant at first, but his love for the series convinced him to take on the challenge. The most exciting part of the film is watching Hiccup and Toothless fly together. Filmed in Scotland and Finland, these scenes feel more real and lighter than anything in the animated movies. When they shoot out of the sea and glide through the clouds, it’s as thrilling as a roller coaster.

Hiccup, a frail boy from a Viking village, tries and fails to defeat the dragons attacking his home. Instead, he forms a close bond with the powerful Night Fury. By breaking Viking rules and befriending a dragon, Hiccup changes his own future and challenges his people's beliefs. The heartwarming bond between the protagonist Hiccup and the dragon (Toothless, known as Tooth in Japanese), and the tender connection between Hiccup and his strict father. In this film, the nonverbal Night Fury, Toothless, is captivating, with mannerisms reminiscent of a cat.
