The Grandfather Paradox


Quick stats about the movie

A sci-fi comedy short that explores the infamous causality paradox: if one is able to travel back in time and succeed in killing his grandfather before he can reproduce, who exactly is it that travelled back?

Indeed this is the predicament Professor Thaddeus finds himself in. His grandson has travelled from the future to solve this paradox once and for all.

As rumor of the grandson’s visit runs through the university, students pack Professor Thaddeus’ classroom to see who will be proven right. Based on Edward M. Lerner’s short story Grandpa?

Personal statement

Director Jean-François Da Sylva says:

“In 2004 I came across Ed Lerner’s short story Grandpa? I couldn’t believe how much entertainment could be packed into a mere seven pages. I contacted Ed and told him of my intention to turn it into a short. To my great relief he enthusiastically agreed.

Throughout development and production, my aim was to stay true to the story, to be faithful to the tongue-in-cheek humour that makes his story so charming. I was very much aware that I was telling a joke, and I wanted it told properly. The most important factor was to make sure that the events felt real.

I didn’t want my audience to laugh because the F/X were awful. I wanted them to laugh because it’s a smart, funny story.”
