Aquarion Movie: Ippatsu Gyakuten-hen  

Gekijouban Aquarion: Ippatsu Gyakuten Hen, 劇場版アクエリオン -壱発逆転篇-

The film you're referring to is a reinterpretation of the television program; it consists of two 2007 OVAs, which have been combined and modified to enhance the narrative flow. Additionally, there's an additional segment that closely resembles a typical TV episode, in which the characters are assigned the task of studying flowers. While the plot has some variations compared to the original series, it remains true to the essence of the story.
