Rocks and soil begin to collapse all around Carlson. When he climbs back up to the rim of the crater to Barbara Rush, he doesn't have a speck of dust on his clothes. Then a few shots later (seconds) he does have dust, then he doesn't. See more...

It Came from Outer Space (1953) - 2 with pictures
Screenshots of mistakes that have been online for less than a year are only visible to members, but the rest are available to everyone. Don't forget to check out the picture of the day, updated daily, and the top 30 screenshots too.
Visible crew/equipment: Opening credits (also a few minutes in) has a fiery spaceship crashing into the camera for this was a 3D movie. What's interesting is that a mirror can be seen on the left portion of the screen just before the collision. This was apparent at the theatres and on the VHS tape release. For some reason, the DVD release has it cropped out and now the spaceship is off-centered at the beginning (fortunately the bonus material still shows it).
Visible crew/equipment: The alien takes a stroll through the Arizona desert after crashing. The animals are frightened and run away with the exception of the owl. The bird has a string tied to its left leg and someone off camera yanks it, and the bird screeches and does a complete flip while flapping its wings. It looks hilarious - poor owl.
