Anachronisms: When the orphans watch King Kong (1933), the giant ape peels off Ann Darrow's clothes. That scene was cut shortly after the premiere, and was not publicly available until 1971.
Anachronisms: In the last scene, at the railroad station, railroad cars from the 1960s or later are on the adjacent track.
Continuity: When Wally, Candy, and Homer leave St. Cloud's for the first time, Candy is lying down in the back seat. When they drive down the dirt road, she is sitting up. In the next shot, she is lying down again.
Anachronisms: The scenes at the drive-in feature a full cinemascope-sized screen. Cinemascope was not available until 1953.
Revealing mistakes: When Homer is learning how to pick apples, a string is clearly holding an apple onto a branch. When he picks it, the string dangles from the branch.
Factual errors: In the end credits, the town of Lenox, Massachusetts is spelled "Lennox".
Continuity: The rules that Homer "reads" do not match the typed list we see.
Audio/visual unsynchronized: When Candy and Homer are visiting the beach, you can hear breaking waves, but the sea is calm.
Crew or equipment visible: When Homer talks to Rose while she is doing the dishes, an actor's mark is visible on the floor.
Anachronisms: The package containing Homer's doctor bag bears four examples of a stamp honoring railroad engineers that was released on April 29, 1950.
Continuity: As Wally and Candy arrive at the orphanage, Curly can be seen running down the steps to approach their car. He looks as if he's helping to open the door, directly in front of Candy. However in the next shot Curly's seen running in from the left to introduce himself to Candy.
Anachronisms: The convertible used in the movie appears to be a 1947 model, which wasn't available in 1945.
Audio/visual unsynchronized: As the train pulls up to the station at the beginning of the film the clang of the bell on the train corresponds to the engineer pulling the lanyard to swing the bell except for the last clang, the lanyard is not pulled.
Factual errors: Several wooden lobster traps, including the one that Candy picks up, have no cement weights at the bottom, making them unusable.
Errors made by characters (possibly deliberate errors by the filmmakers): Homer mentions that he has never seen the ocean, yet when Fuzzy is buried, there is clearly an ocean in the background.
