Continuity mistake: In the scene where Merlock rips apart an upstairs guest room in the form of a bear, the floorboards beneath Scrooge and Genie run in two separate directions from one shot to the next. Initially they're running perpendicular to the window - but once Scrooge urges Genie to return to his place inside the lamp, they're shown parallel to the window instead. (00:47:05)
Continuity mistake: In the prison cell where Scrooge is staring at his money bin through the rain and lightning, his left hand grips a different window bar between shots. (00:51:00)
Continuity mistake: Before Scrooge is cast out from Merlock's fortress in the sky, he loses his top hat over the edge. A few moments later when he and Merlock are falling back to Earth struggling over the magic lamp, Merlock loses his talisman. Here you can see, for a moment, that Scrooge is once again wearing his lost hat. (01:05:00)
Audio problem: In the final scene where Scrooge chases Dijon out of his money bin, Scrooge shouts, "I'll change your face, you thief," but his mouth isn't even open. (01:09:10)
