Continuity mistake: There is a scene when they are all in the press room when he's inside the desk. As Hildy goes to get water you can see she's wearing the black heels she's been wearing throughout the movie. In the next shot as she walks behind the table, if you look through the table legs you can see she's wearing a pair of flat white slippers/loafers.
Continuity mistake: When Earl Williams and Hildy are in the press room, she locks the door and lowers all the shades. Then Molly Malloy knocks and is let in. Suddendy, all the shades are raised up again. (01:35:20)
