The live-action movie "How to Train Your Dragon" (2025) does have a post- credit scene, but it is extremely brief and somewhat underwhelming compared to typical post-credit scenes. The scene appears at the very end of the credits and shows Hiccup sitting with the Book of Dragons. He places his personal notebook, containing a drawing of Toothless, on the page labeled "Night Fury," which was previously blank earlier in the film. Hiccup taps his fingers as if contemplating the drawing, and then the scene ends. This post-credit moment is essentially a callback to a moment already seen in the movie rather than a teaser for the sequel. It is more symbolic, hinting at Hiccup's future with Toothless and the exploration of dragons in the next chapter of the story. Unlike many franchises, it does not reveal any new plot details or set up the sequel. The sequel, expected in 2027, will likely follow the storyline of the second animated film. Overall, the post-credit scene is very brief and does not provide major new information, so you do not lose much if you leave before the credits finish. However, it is a franchise first, as none of the original animated films had a post-credit scene like this.
