The film featured the Anime Debut of Hawks, who would make his First Appearance in the TV Shows a Few Months later after the Films Release.
When the Film originally premiered in Japan, Deku uses his Shoot Style ability before actually learning in the TV Show. The film released in America 1 Week after Deku learned the Power Up, making it much less Jarring to see him use it without an Explanation.
The streaming version of Heros Rising ( via Starz), has a different audio line in the dubbed version. Mina Ashido says "Go get'em Chargezuma!" At around 07:15 into the movie. However, the line in the dubbed version on DVD, she says "Go get'em Chargebolt!"
When the volume is turned up high on on any device that you stream or watch it on, a distinct beeping noise can be heard coming from background of particular scenes such as when nine goes beyond his limit and conjures a tornado. Some providers have noticed this yet they are unsure to whether this is a glitch in the sound or embedded. Still the issue has been raised to some and may have price drop it due to this 'glitch'.
