Factual error: Alva and Owen go see the movie "One Way Passage", released in October 1932. The movie takes places in August, the year is not stated explicitly, but there's a wall calendar in the dining room at the boarding house (you can see it when Legate leaves, calling himself a fink) for 1934, and at the same time the date shown in the office (when Redford sits at the desk to decide who will get pink slips) is August 14, Friday, which would set the movie in 1931.
Continuity mistake: Robert Redford has no cigarette before jumping off the train passing by Dodson, suddenly has a lit cigarette in mouth, then not, then one in hand that he tosses away. What he does not toss is his suitcase before getting off the train. But his luggage is there for him anyway right after. (00:06:20)
