In 2002, Namco produced a CGI animated film based on the classic game Xevious. It was shown for one week in a single theater, and then it was gone forever with no trace of it to be found.

I came across the trailer for this inaccessible film, the most footage from the Xevious movie that anyone outside of Japan had ever seen.

This video is all about the movie: where it came from, what it was, where the trailer came from, and whether the movie will ever be seen again.

The raw video from the disk may be found at https://archive.org/details/01_20240617 .
The trailer on it's own may be viewed at    • Xevious Movie Trailer (2002)   .
