Dragon Ball Super: Broly

The hype for this film was so high that the tickets were sold out in Japan, 5 months before the official release.

It's implied here that Frieza was the first one to use Scouters, as he offers them to the Saiyan army as part of their service to he and his father's organizations. But flashbacks in the original Dragon Ball Z anime clearly show that it was the Tuffles (the other race living on Planet Vegeta before the Saiyans wiped them out) who first used them, as a means of identifying their invading foes.

Does not include a post-credits scene. However, the closing credits play over footage of characters featured in the film.
