Well, off the top of my head… the teal-washed version of Aliens.
You mean the non teal-washed version, right? 😃
Despite the horrific teal vandalism visited upon the Blu-Ray and HDTV broadcasts, the original isn’t lost though. I own the 1999 NTSC SE DVD and there are tons of copies available to purchase brand new.
According to this blog, the original theatrical versions of the first two Godfather films are lost, due to irresponsible behaviour during the first 80s home video transfers, colour correction “guidance” imposed by Gordon Willis upon Robert Harris’s team during the “Coppola Restoration” and then Paramount’s destruction of the original negatives once the project was completed.
Makes for depressing reading.

Yeah, but only as an SD master. Every HD version has been teal-ified.
