Corrected entry: Right after the 15 puppies are born, Roger is holding the dead puppy who is brought back to life. He then tells off Cruella, saying she may not have any of the puppies, and the sickly puppy is still upstairs with them. Pongo then runs downstairs to tell Perdy that Cruella is gone, and next to Perdy are 15 puppies. Shouldn't there be 14, considering the 15th is still upstairs?
Corrected entry: When Cruella is writing the check with her "wretched" pen, the colors of her hair are on opposite sides from normal.
Corrected entry: In the scene where the two robbers are following the puppy trails through the woods and are nearing exhaustion they spot the police convoy coming along the road. The cars appear to be mostly Range Rovers. In a latter scene though, Cruella joins them in the prison van and the convoy of police cars is seen to be leaving the village, but most of the police cars appear to have changed to Land Rover Discovery's, instead of the earlier Range Rovers.
Corrected entry: Cruella is in her bed reading the paper about her robbery. When she says, "Roger, you are a fool.", her gray eyelids are colored white for one frame, causing a blinking effect.
Corrected entry: Roger walks down the stairs imitating Cruella. He has a long cigarette holder & cigarette in his hand. But two seconds later, they are gone.
Corrected entry: The first time Cruella shows up at Roger's house she has a cigarette in her left hand. In the next shot it's in her right hand.
Corrected entry: When Pongo is watching the dogs being walked he is looking down out the bay window. In the next scene he has to run up the stairs to get to the front door.
