This is one of the most darkest movie I have seen from the Pixar yet. Borrowed Time, a short film that Pixar animators Lou Hamou-Lhadj and Andrew Coats made as a side project. The piece, which has toured film festivals and is now available on Vimeo for a limited time, is expressly about loss and mourning.
“A goal for us was to make something that kind of contested the notion of animation being a genre, and one for children specifically,” Hamou-Lhadj says in a making-of short that debuted on Vimeo alongside Borrowed Time. “We really wanted to make something that was a little bit more adult in the thematic choices, and show that animation could be a medium to tell any sort of story.”
