Movies like Akira, Spirited Away, Spider-Man: Into the Spider-Verse, and Ratatouille often come up in discussions of the all-time best animated films. However, most people can’t separate the idea of ‘best animated movie’ and ‘movie with the best animation' and Redline will always be the answer when discussing the best animation quality in a movie. You might not have heard of Redline, which wouldn’t be surprising. Despite Madhouse Inc. producing some of Japan’s most popular animes to date, Redline has rarely come up in discussion until recently— the film's unmatchable animation quality resulted from a seven-year effort, and it almost destroyed its creators.
