expose the creature directly to the ship's nuclear pile. It easily crashes through the door and escapes. The creature is so strong that it can tear through the metal hatches separating each of the ship's levels. The survivors (except for an injured crewman, who is trapped below in a spot inaccessible to the creature) retreat to the control room on the topmost deck. When Carruthers notices the ship's higher-than-normal oxygen consumption rate, he surmises that this is due to the creature's larger lung capacity, needed for the thin Martian atmosphere. In a last desperate move, everyone puts on their spacesuits, and Carruthers opens the command deck's hull airlock directly to the vacuum of space. A violent decompression follows, and the plan works: "It" suffocates and finally expires, stuck part way through the final hatch. A press conference is later held on Earth, revealing the details of what happened aboard the rescue ship. The project director emphasizes that Earth may now be forced to bypass the Red Planet "because another word for Mars is Death". Cast Marshall Thompson as Col.

Principal photography took place over a two-week period during mid-January 1958. Small kept changing his mind over whether or not he wanted plastic eyes installed in the creature's mask, causing a lot of aggravation for the film's makeup artist, Paul Blaisdell. It! was the last film of actor Ray "Crash" Corrigan. Corrigan was set to play the creature, but during pre-production, he did not want to travel over to Topanga Canyon in western Los Angeles County where Paul Blaisdell lived and operated his studio. Therefore, Blaisdell could not take exact measurements of Corrigan's head. Consequently, there were final fit problems with the creature's head prop: "[Corrigan's]...bulbous chin stuck out through the monster's mouth, so the make-up man painted his chin to look like a tongue." Blaisdell then added a bottom row of fangs that covered Corrigan's jutting chin. Blaisdell said working
