Errors

 * As the Turtles were entering the Imperial Science Museum from the underground tunnel, Leonardo had Raphael's colours. He later had Raphael's colours when first dueling Moriarty with his katana.
 * When the 19th century nightwatchman said that the observatory wasn't open to turtles, a shot of the Turtle's London sewer lair wall was seen behind him.
 * When finding the secret entrance to Moriarty's hideout, Raphael was seen with Leonardo's colours.
 * When the Victorian policeman entered the observatory it was daytime outside even though the atomic clock theft happened at nighttime.
 * When Holmes' bust landed near Michelangelo on the floor, his nunchuks were upside down.
 * Holmes' bust was missing from the window when Watson took cover.
 * When the turtles stand up after taking cover, Michelangelo has Donatello's colours.
 * When Donatello drew his bo to duel Holmes, it showed the background of the Turtles exiting the sewers into Moriarty's alternate 1991 instead of the flight of steps that led to the observatory.
 * When Leonardo examines the soot trail, the spectacles the turtles were wearing as part of their disguises have disappeared for a brief shot. They then disappear completely once they enter the sewers.
 * When Leonardo shouts "Down that alleyway!" after the air gun cane smashed the tea room window, he and Donatello's colours were switched.
 * The turtles lose their hats after jumping into the river. But after they meet up with April and she goes to open the secret book case passage they have their hats again.
 * When Raphael says "Nice save, Leonardo" after returning to their own time, his mouth doesn't move.

Quotes
