    • Equipment Visible: When the sergeant turns the periscope to see the Doctor, Ben and Polly, the boom mike creeps into the upper right corner of the shot.

    • Revealing Mistake: The arctic base's periscope shifts around when the TARDIS materializes nearby.

    • How can Earth and Mondas have identically shaped land masses, as each planet has been separately affected by continental drift for millions of years?

    • Factual Error It is always seen snowing in Antarctica. Given its high altitude, the Antarctic air is very dry and precipitation is rare.
