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.
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.
Continuity mistake: After Scrooge props open Collie Baba's treasure chest only to discover that it contains nothing but clothes, he tosses them one by one onto Dewey - who's standing in between Huey and Louie. But a few frames later when Scrooge is through emptying the chest, Dewey stands in Huey's place without a pile of clothes on his head.
Continuity mistake: Before Merlock escapes from the temple with Collie Baba's treasure, he throws a switch that begins to lower Scrooge and the others into a pit of giant scorpions. Now they have no choice but to use the tethered basket as cover (which, at one point, was loaded with treasure). So Huey, Dewey and Louie break out their pocket knives and start cutting away at the ropes. But between shots, Dewey and Louie instantly switch places with one another. And after Launchpad flips the basket over everybody's head like a turtle shell, all of the remaining rope fragments disappear from the platform.
Continuity mistake: When Genie is in the boys' bedroom frantically looking for a hiding place to avoid being spotted by Scrooge, Huey opens the closet door. Behind him is a computer table with its top drawer pulled open. Once Scrooge enters the room and starts asking questions about a ruckus downstairs, a set of headphones appears hanging from the drawer's edge all of a sudden.
