The live-action "How to Train Your Dragon" movie does have an after-credits scene, but it is very brief and not a new or major scene. After the credits, there is a short moment where Hiccup is seen sitting with the Book of Dragons. He places his personal notebook, which contains a drawing of Toothless, on the blank page labeled for the Night Fury. He taps his fingers a couple of times, seemingly contemplating the drawing. This scene is essentially a callback to something shown earlier in the movie and serves more as a symbolic gesture rather than teasing new story developments or a sequel. Unlike many modern movies, it does not include a mid-credits scene or an extended post-credits setup. The scene lasts only a few seconds, so it is not necessary to wait through the entire credits unless wanting to see this small symbolic moment.
In summary, the after-credits scene is a quiet, brief moment focused on Hiccup's sketch of Toothless in the Book of Dragons, with no new plot revelations or sequel hints.
