Continuity mistake: When Bugs leads Yosemite Sam and his dragon into the tower containing the explosives, you can see Bugs is holding the Swinging Sword. But when he traps Sam and the dragon in the tower, the sword is missing, and when Bugs is walking away from the castle, he has the sword in his hand again.
Continuity mistake: When the dragon sneezes and sends the tower of the castle up to the moon, the two windows at the top of the tower change position between shots.
Continuity mistake: When Bugs Bunny walks away from the castle, we hear the dragon sneezing that sends the tower going up into space. At this point, you can see that there two windows on the bottom half of the tower, but when we see the tower in the next shot, there are now three.
Continuity mistake: When King Arthur says "A good idea, fool!", Bugs Bunny stops and you can see that behind him is a wall. In the next shot, Bugs is now in front of King's Arthur's chair, and when he says "Beheaded?" he is back in front of the wall again.
