In the 1964 James Bond movie Goldfinger, a section of Main Street appears in the film. In the scene where Goldfinger's men are driving in Army trucks on their way to Fort Knox, they can be seen coming out of Harris Street turning onto Main Street. The red brick house on Harris Street, the white cinder block building on the corner of Harris and Main, and the Used Cars sign in the background are still there today.

Muldraugh and its neighboring town West Point both serve as starting towns^[8] for the 2013 early-access open-world zombie survival-horror video game Project Zomboid. While in-game, the player can explore and loot a close representation of the towns that include both existing and fictional landmarks and locations. It is possible to leave these towns and follow the Dixie Highway north, where one will eventually end upon the quarantined city of Louisville, the most extensive and diverse settlement within the game.
