- Dennis Hill was born on July 19th, the exact date his first cartoon debuted on YouTube.
- Dennis's middle name is "Dio".
- Cinema Worker was meant to be a one-off cartoon, but due to the positive reception of the character, more cartoons were made featuring Dennis — eventually leading to a full series.
- Dennis’s cat, Bailey, is based on Andrew’s real-life cat, also named Bailey, who passed away in 2022. Her meows in the cartoon are archival recordings from when she was still alive.
- The Dennis Hill Saga is the first official series from Smokey Joe Cartoons.
- Cinema Worker is the only Dennis cartoon to be released on YouTube completely uncensored.
- Mr. Ross (Dennis’s boss) was inspired by J.K. Simmons’s performance as J. Jonah Jameson in the Spider-Man film series.
