In the montage showing Abby and Rodney living the high life after they are married, the image of William Deane signing Rodney's $4000 allowance check with the same date (October 15th, 1932), and the same check number is used twice, even though several months have supposedly passed between checks.
In the montage depicting Rodney going to the horse races instead of work, one shot shows Churchill Downs in Kentucky with its distinctive twin spires on the grandstand - which is nowhere close to New York City, of course.
