Visible crew/equipment: At the start, when Lucy pulls into the "gas station" the thin cable pulling the Pontiac is visible in front of the car, and when Ethel walks in front of the car note that the actress quickly glances down and steps over it, just as she says they're lost. Additionally, the glass windshield and rearview mirror are gone.
I Love Lucy (1951)
1 visible crew/equipment mistake in Tennessee Bound
Starring: Lucille Ball, Desi Arnaz, Vivian Vance, William Frawley
Revealing mistake: At the Brown Derby, when Lucy bumps into the waiter causing him to trip and spill the tray all over William Holden, we can see that the waiter's hand is taped to the bottom of the tray for the stunt to be done efficiently. (00:15:15)
Ricky Ricardo: What's the matter with you? Are you crazy or something?
Trivia: Lucy, Ricky, Ethel, and Fred all do the impressions of Maurice Chevalier. Thirty-six years later, the same impression is done in the 11th episode of The Simpsons.
