Goofs

Will Hamilton's shorts are visible at one point as he is drying off and talking to Cal after his shower.

Towards the end of the movie, the window that Aron breaks is different between shots.

Aron's hair changes from the shot when the sheriff is on the Albrecht's porch (just after the fight) to the next, when he asks Abra "Where were you?"

Cal follows the lady who turns right into a lane opposite the water tower, and he runs to the corner and looks right. After the cut, he comes running from the other direction to look to his left into the same lane.

While Cal is talking to Abra on the roof, in the close-ups, the light in her bedroom is seemingly on, whereas in the wide shot, her room is pitch black.

Abra tells Cal she can go to Adam's birthday party the next day because she gets an hour off for lunch from the Hospital. Somehow, she had enough time to cook a turkey because just before the party, she tells Cal it's almost ready. However, it's not impossible to believe that Cal started the turkey earlier, seeing as the household is a father and two sons. One of them must know how to cook.

Kate writes the $5,000 check and puts it in the blue envelope, licks it and presses it to seal. However, when she hands the envelope to Cal, it is unsealed.

The "refrigerated" railroad cars are obviously just regular boxcars with temporary banners on their bracing. This is most evident in that they have single sliding doors, rather than double hinged doors as refrigerator cars at the time had.

When Cal goes to Kate's bordello/saloon to have a drink, the young gal working as a server questions whether he's old enough to be in such an establishment calling him "just a kid". James Dean was 24 years old when he made this movie, far too old to be considered a "kid".

In 1917, Adam Trask unsuccessfully "invents" the refrigerated railroad car to ship produce. In reality, tens of thousands of such cars were in common use by 1890 (this mistake was also made in the novel).

During WWI, a band organ at the carnival plays "Ain't She Sweet", which is from 1927.

The film is set in 1917, but the hairstyles of both Cal and Aron are both obviously contemporary hairstyles of young men in the 1950s.

During WWI, a band organ at the carnival plays "Ain't We Got Fun", which is from 1921.

In one scene, a band plays "Avalon". The film is set in 1917. "Avalon" was not published until 1920.

After his fight with Aron, Cal goes into a bar to get drunk, a short time after arriving, he says to the barman "Fix me another drink," Cal's lips don't move when he says that.

When Cal is leaving Kate's office, we can hear the doorknob, but in the mirror on the wall we cannot see him.

When Cal leaves home after a fight with his father, Aron asks, "You coming home tonight, Cal?" to which Cal responds, "What's the difference? You're home, ain't ya? You're the one he wants." Cal's mouth never moves, though it's partially masked by him putting on a sweater.

When Hamilton says, "He's crazy!" during Cal's dance in the field, his mouth doesn't move.

When Adam Trask is being shown how to operate the car he is going to buy, the mechanic takes Adam to the front of the car to show him how to use the manual hand crank. You can see the boom mic in the reflection of the car's front windshield.
