Here’s an eight-minute short film which Guillermo Del Toro directed in 1987 called Geometria, the story of a boy who is failing geometry and decides to use black magic to summon a demon in order to help him (because, hey, why not?). Del Toro has always said he never liked this, but it’s actually quite a fun little short which builds to a clever twist ending. It’s also hilarious to see the short open with the title “Una Presentacion de Samuel L. Bronkowitz”. It seems like Del Toro must be a huge fan of The Kentucky Fried Movie, as all the fake trailers and movies showcased in that film were produced by Samuel L. Bronkowitz.
