Well, it looks like Columbia pictures is going a bit overboard with the DMCA requests. I mean really, taking down videos just because they have the same name as your Movie (And they were out long before the movie!)
Among the casualties of the DMCA was a video project called “Pantone Pixels” and a 2006 video produced by an NGO called “Pixels.” Also pulled down was a short film (seen above) called “Pixels,” which is the inspiration for the Hollywood production.

Update: Evidently, the company that was handing out the DMCAs have withdrawn the DMCA requests. I’m guessing that someone at the company set a bot to do a far too general search, hopefully something like this doesn’t happen again in the future.
