This one’s called The Adventures of Andre and Wally B, Pixar’s first animated short from 1984.  Well, not Pixar exactly since it was done mainly at Lucasfilm, but the creative team did include John Lasseter and some of the Pixar heavies.  It’s hard to envision the promise they would later show from this, but keep in mind this was made in 1984, so creating it probably took three flatbeds filled with punchcards, adhesive glue, and a live chicken.
