Continuity mistake: In this scene we see several Government Officials talking in a room. One of them, while talking, is playing a game. The game is to balance the lid of an ink bottle on the end of a ruler and over the ink bottle. When the ruler is flicked rapidly gravity would do the rest and the lid would fall into the ink bottle. Things don't work to plan and the lid falls on its side. In the next wide shot, the lid is right side up and a little distant from where it fell earlier.
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: In one shot of the auditions at the radio station, the sign on the desk reads "Jack Bunny and his Amatuer Hour." In other shots, the error is corrected.
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: 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)
