劇場版プリパラ み～んなあつまれ！プリズム☆ツアーズ
PriPara Movie: Minna Atsumare! Prism☆Tours is the film based on and starring the characters from PriPara. The film first began showing in theaters across Japan from March 7th, 2015. The plot focuses on Laala Manaka finding out about Saints' top idol journey, and aside from the PriPara performances, the movie also features the journey of characters across all the Pretty Rhythm series.
At some point in the movie, the characters are given a choice of four doors to go through. At this point, the movie diverges into one of 4 routes depending on what the audience chooses. Each route recaps different aspects of the previous Pretty Rhythm series, mainly reintroducing the different characters and their performances. However, Laala and friends only get a chance to enter one door at a time, meaning the film must be watched four times to view each door choice.
