During the prison escape when Jean Harlow and friend hop into the getaway car, the seat backs are already wet before the two drenched escapees get into the auto. Obviously this was a second or third take of this scene.
The girls escape prison by running out of the kitchen and jumping into a large drain pipe in the middle of the prison yard, getting washed through the pipe and emerging by a river. Yet the Harbor News article states that they "...escaped Tuesday morning down the drain-pipe leading from the roof past the cell in which the escape was maneuvered," which makes it sound like they shimmied down a normal gutter drain.
