Yes, the live-action movie "How to Train Your Dragon" (2025) does have a post- credit scene. It is a very brief scene where Hiccup is seen sitting with the Book of Dragons. In the scene, Hiccup opens the Book of Dragons to the blank Night Fury page and places his personal notebook, which contains his drawing of Toothless, on top of it. This scene is symbolic and references a moment already seen in the movie, but it doesn't reveal new information or directly set up the sequel. It comes right at the end of the credits, so viewers need to stay through the full credits to see it. The post-credit scene is more of a quiet, reflective moment rather than an action-packed teaser or a major reveal.
