Best animated movie mistakes of 1941
Continuity mistake: When you see Perry White’s hand go to his radio to call Clark and Lois into his office, the face of the radio is seen. Then it fades to a different view of him talking to Clark and Lois, and his radio is still seen, only now the space between the top of the radio and the speaker has gotten smaller, the sides smaller, as well as the space between the speaker and the switches he was pushing.
Continuity mistake: When the lady on the radio calls for two fresh eggs to be added to the recipe, Donald says "Just a minute!" and goes out to get some from the hen. You can see that there is nothing next to the baking powder shaker, but in the next shot a salt shaker has suddenly appeared.
