Continuity mistake: During the visit of the Minister in jail, Charlie sits next to the Minister's wife. The distance between them varies between shots. (00:30:40)
Continuity mistake: After the bad guys frame Cagney for drunk driving and stage an auto accident, the smudges on his face change shape and position several times between shots. (00:27:30)
Continuity mistake: In the scene where Louisa Cody moves from the railing of the boat and stands at a doorway and looks into the room, to see her husband Buffalo Bill Cody is sitting at a table with others. In the very next shot she is back at the railing of the boat and looking back into the room.
Continuity mistake: During the auditions at the radio station, the wording on the window reads "Gong Broadcasting." But in a shot of Owl Jolson seeing Jack Bunny at his desk, the wording reads "Gong Broadcasting Station."
Continuity mistake: The lawyer and his two collaborators arrive in Mandrake Falls and reach Longfellow Deeds' home. The housekeeper opens the door to let them in...and never bothers to close it (and it does not close by itself). Few seconds later, Deeds' arrival is announced by the dog who impatiently paws at the closed door. (00:04:50)
Continuity mistake: Todd meets Mr. Beadle outside of his shop with a new apprentice for him. Beadle strokes his chin as he mentions the 7 guineas, but his hand is firmly on the boy's shoulder at the cut. (00:07:55)
Continuity mistake: At the end of the establishing continuous shot in the lobby, Bert leans against the desk and whines; "This is the kind of night that gives me the willies." The clerk rolls her eyes; she is holding a note between the two hands and you can see right before the cut that the note stays in her left as she lets go with the right. The new shoot though begins with the note in her right hand. (00:02:45)
Continuity mistake: When Porky Pig falls asleep in his boat, he is wearing a red shirt. In his dream, a big fish cuts off the red shirt to cook a now naked Porky. When the dream ends and Porky wakes up back on his boat, his red shirt is still missing, and he's still naked. He should have still had his red shirt on.
Continuity mistake: When we see "Ben Birdie" on the stage at the start of the cartoon, he is surrounded by a piano, tuba and a drum, but when a mouse appears out of the tuba in the next shot, the drum has completely disappeared.
