When Shep (Humphrey Bogart) and Lenny (Lyle Talbot) stop fighting, Shep's handkerchief is half out of his pocket. In the next shot, it's nicely tucked back in.
Humphrey Bogart goes to the drinks table with his newspaper pointing outwards; then it's instantly pointing at his feet.
When Shep Adkins (Humphrey Bogart) is being introduced, his hands instantly change from holding a newspaper behind his back, to holding it at his sides, then behind his back again.
At the train station, prior to Bud and Vida saying goodbye, the stops for the North Shore Limited (Track 28) and The Puritan via Short Line (Track 29) are shown. While the Track 28 route follows a logical geographical progression from Stamford, CT to Boston, MA (via Bridgeport, New Haven, New London, Westerly and Providence), the "Track 29" cities are out of "order". Instead of Syracuse-Albany-Utica-Rochester-Buffalo-Toledo-Erie, the board should read Albany-Utica-Syracuse-Rochester-Buffalo-Erie-(Cleveland)-Toledo. (It is beyond belief that the train would not stop in Cleveland, the most populous city, according to the 1930 census, of all those listed.)
