Here by Richard McGuire was a short. 6-page comic published in 1989 in Raw magazine, the groundbreaking anthology edited by Art Spiegelman & Françoise Mouly. McGuire later expanded Here into a 2014 graphic novel.
This is a 1991 short film based on the short comic version:

The forthcoming Zemeckis feature film with Tom Hanks & Robin Wright is supposedly adapted from the graphic novel version of Here, though it looks like it may include a more conventional story, something the McGuire versions don't have. Zemeckis may just have used McGuire's concept as a springboard.
