A limited budget require the use of stock footage of the spacecraft from Flight to Mars , but the new footage is effective - especially when a brave astronaut is shown walking down the length of the ship in an attempt to get behind the monster. The interior of the rocket is vertically multi-leveled, each level housing a different section, such as control room, lab, crew's quarters and storage.
Stairways connect each level which can be sealed off from the other by metal hatches.
