Best short movie factual errors of all time
Factual error: The adventurers witness Earth "rising" from behind the lunar horizon. Since the Moon is tidally locked, it always presents the same hemisphere toward Earth. Earth never rises or sets as seen from the Moon's surface; it stays stationary in the sky. No matter that no-one had travelled to the moon at the time - that fact can be deduced just by looking at the moon from earth, and noting that we only ever see one half of it.
Factual error: As the beginning shows Krypton explode, there is a huge cloud of dust at the remains of the planet that then fades to nothing. Only space dust would not act like that from an entire planet exploding. It acted like dust settling on the ground and just fading away, rather than dissipating into space.
Factual error: Oliver Hardy, inside a telephone booth, looks up Stan Laurel's number in a large directory. He finds the number on a page which is about one-fifth of the way from the beginning of the book. After he calls Stan and Stan hangs up on him, Ollie looks up the number again. This time he finds the number on a page which is about three-fourths of the way from the beginning of the book. Names beginning with "L" would not be on either of those pages but would be approximately two-fifths of the way into the book.
