Corrected entry: When Scrooge tells Dr. Honeydew and Beaker he doesn't want to donate to charity, Beaker gives Scrooge the middle finger when they are leaving. (00:14:33)
Corrected entry: When Bob Cratchit asks Mr. Scrooge for Christmas Day off, he explains that all businesses will be closed and he would have no one to do business with. But when Scrooge wakes up from his last spirit, he asks the little mouse to get the prize turkey out from the window. I thought all shops were closed on Christmas Day as Cratchit had previously said.
Correction: The butcher was closed. But back then, it was common for people to live and work in the same building. So the butcher could be roused and the arrangements made with little trouble. The butcher might very well demand a bit of extra pay for his trouble, but the point is that the shop being closed is hardly an obstacle.
Corrected entry: In the scene where Jacob and Robert Marley visit Scrooge, they mention children from an orphanage having teddy bears. This wouldn't have happened in Victorian Britain as teddy bears weren't introduced until the early 20th century.
Correction: It was only named 'the teddy bear' in the 20th Century (Teddy Roosevelt), but it did exist in Victorian times, except it was referred to as just a stuffed toy.
Corrected entry: In the beginning, when Rizzo says something like, "A blue furry thing can't possibly be Charles Dickens", look at his left arm and you can see a wire moving it.
Correction: It's a puppet. That's how it works.
Corrected entry: At the end when Scrooge brings the turkey to the Crachet's house, the turkey is raw. But moments later when they all sit at the table it is already cooked.
Correction: Actually, it isn't moments later - we see Scrooge and all the Muppets enter the house, then there is a shot of outside where Gonzo/Dickens tells us what happens after this. Then when the camera cuts back into the house, everyone is settled at the table and some of the people who were first there have left, so we know at least some time has passed, possibly enough time to cook the turkey.
Correction: It only looks that way. Beaker, like most cartoon characters even though he's not technically a cartoon, only has four digits on each hand.
