Two characters from Mark Garvey's "Bucket" (2007) resurface in "Patchwork" (2014): the Delivery Driver (played by Paul Woodcock) and Presto Hume (played here by Hugo Oakley, originally played by James Newman).
The character "Safety Man" played by Ian Tucknott wears a "Nothing-Men" T-Shirt. This is a comic/graphic novel by the film's director, Mark Garvey.
