Grundy Gunthrie is a fictional character played by Stéfane Samson in the 2017 film, Bigsby, and the 2018 film, Grim.

Grundy appeared as a member of a bum fight audience in "Bigsby the Fighter", he is then seen attacking G.G at a punk show in Grim.

Development and Casting
The character was created by Fritz Bishop in his initial draft of a script for Grim, named after a character he would create in wrestling video games as a child. The role was specifically written to be portrayed by Stéfane based on his performance in Bigsby,

Stéfane appeared as an unnamed background character in Bigsby, but Fritz decided to retroactively acknowledge that the character was the same that Stéfane portrays in Grim. At some point between the events of Grim and Bigsby, Grundy cuts his hair and appears to have developed a friendship with Ian Obscene, as they are seen attending bum fights together.
