What's It To You? Mylar (also known as Mylar: What's It To You?) is an industrial short produced by the DuPont Corporation in 1955 to promote their brand of polyester film.
The short was intended to be used for the Mystery Science Theater 3000 CD-ROM, but that product was never completed. The master tape was apparently misplaced at the Best Brains offices, and has not re-surfaced.
Trace Beaulieu made brief reference to the short during a promotional spot that aired during Turkey Day '95.
