I saw this in theaters when it was out on a limited release. Love the overall 50s theme. Mr. Theopolis was the best with that cliched 50s "bachelor" look. Mr. Robinson obsession with not coming back as a zombie made him funny and just sad like when his wife tells him their having a kid he already planning for its burial.
Recall Mrs Robinson got annoyed with Mr Robinson and said to he "Well we're coming back as zombies, right Timmy?" ... "Right Mom!"
Yeah the guy that played Mr. Theopolis (Tim Blake Nelson) played the simple minded Delmar in "Oh, Brother were art thou?" He was just as funny in Fido as he was in Oh, Brother.
The move has some great lines in it ...
Bill Robinson: I'd say I'm a pretty darn good father. My father tried to eat me. I don't remember trying to eat Timmy.
Helen Robinson: Bill, just because your father tried to eat you does that mean we all have to be unhappy?
