Yes, there is a post-credit scene in the 2025 live-action movie "How to Train Your Dragon." It comes right at the very end of the credits, so viewers need to stay through the full credits to see it. The scene is very brief and is a continuation of a moment shown earlier in the movie: Hiccup opens the Book of Dragons to the blank Night Fury page and places his personal notebook on top, showing his drawing of Toothless. This drawing is the same one he made soon after meeting Toothless in the film. The scene doesn't tease the sequel but serves more as a symbolic moment, confirming that Hiccup will add the Night Fury's image to the Book of Dragons. It does not contain new footage or dialogue and is largely a quiet, reflective moment.
