Visible crew/equipment: After the demonstration at the blackboard, the big group of soldiers walk over to the big table with the picture of the world on it. As they walk away from the blackboard, they turn and walk down some steps, and as they do you can see the shadow of a boom mic pole on the upper side of the grey part of the wall.

Audio problem: When Dr Forrester and Sylvia are hiding in the farmhouse, just after the Martian eye enters the room, Dr Forrester says "An electronic eye - like a television camera" - however when he says "camera", his lips don't match the word.

Continuity: When Sylvia and Dr. Forrester are in the farm house, Sylvia cooks some eggs, then places the plates of eggs on the table. As she places them down you can see a plate with toast stacked on it. This plate disappears in the next shot of them both sitting down.

Continuity: Look closely when the Martian "spaceships" make their first appearance, underneath are three electro-magnetic legs supporting it meaning they walk rather than fly, much like the tripod war machines in the original book, yet after this scene they can't be seen again. The studio opted to forgo the use of this special effect after this particular shot. (This is best seen on the DVD version of the film.)
