Continuity mistake: When the Wheelers are at Shep and Millie's house, telling them about their move to Paris, Millie reaches over to the coffee table and takes a chip from the bowl. The shot changes to a different angle, and her empty hand is now resting on the sofa, then she reaches over and takes the chip again.raywest
Factual error: When Frank is in the bar/restaurant talking with coworkers, one of them remarks about "the old cubicle." Cubicles were not used in companies until the 1960s. In the 1950s, when the film takes place, companies had rows of desks without any dividers between them.
Revealing mistake: During the first scene of Revolutionary Road, when the main characters are walking out of the school, I noticed smoke detectors on the ceiling.
Factual error: Kate is wearing a watch with a Speidel Twist-O-Flex watch band. These bands were introduced in 1959.
Factual error: The wall phone in Frank and April's 1955 kitchen is an old rotary phone, but actually post 1980. It has a modern flat cord and a modern wire plug. Phones cords in 1955 were round and permanently attached to the handset with no square plug.
