The swastikas on Dorgan's satchel were a traditional Native American sign of "Good Luck", and are not to be confused with their later, better known use as an emblem of the Nazi Party.
This film is the first one made under Edward G. Robinson's 1930 contract with Warner Bros. that called for him to appear in four pictures at a flat $35,000 per picture.
In September 1928, Warner Bros. Pictures purchased a majority interest
in First National Pictures and from that point on, all First National productions were made under Warner Bros. control, even though the two companies continued to retain separate identities until the mid-1930's, after which time "A Warner Bros.-First National Picture" was often used.
Before jumping off the train, Dorgan is seen reading a copy of College Humor magazine, a real magazine published from 1920 to 1943. The cover price in 1930 was thirty cents ($5.70 in 2024) and it was typically 130 pages long at that time.
This film has been preserved by the Library of Congress.
