Factual error: The globe that April shows to the children is post-1992: Czechoslovakia is divided into the Czech Republic and Slovakia, and Germany is united instead of being divided into Eastern and Western Germany.
Factual error: There is a modern drop ceiling in the 1955 hospital waiting room where Frank is waiting after April's miscarriage.
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.
Factual error: The longneck beer bottles in the 1955 beach scene are incorrect. Longnecks are faster to open, so they were designed for and used in bars. Retail beer bottles (that you would see at the beach) before 1980 or so were shorter so they could fit better in home fridge shelves.
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.
Revealing mistake: The magazines in the Wheelers' living room, and Frank's Berlitz guidebook, are dog-eared and browned. They're probably from 1955, but they look like they're 50 or 60 years old.
Factual error: In one of the scenes showing the children's room, there is a horse model on the dresser behind them. The model is in fact a Breyer "Running Mare" in a charcoal color. This model was not produced until 1961.
