Another article on the animation world news site, awn .com highlights City of Rott recently again, at a prior film fest in 2018:
The three Art Park screenings concluded with City of Rott by Frank J. Sudol from the United States. Inspired by the classic zombie films, Sudol’s 2006 feature film is the tale of a grumpy old man and his talking walker who set out alone, unarmed, and losing his mind to buy a new pair of shoes in the city of Rott. The city is infected with hordes of flesh-eating zombies and the crazy old man only has his walker to battle the living dead. Will he fall victim to the Rott Worms that inhabit the zombies decaying brains? The film was entirely created, written, and directed by Sudol who is currently in production on a sequel to City of Rott called City of Rott: Other Worlds. A short trailer for the new film was shown following the feature.
