It! The Terror from Beyond Space (1958)

In the year 1973, a daring expedition to the Martian frontier results in unforeseen calamity. As a rescue party lands on the desolate Martian landscape, they discover a lone survivor - the expedition leader, Col. Edward Carruthers. Shrouded in suspicion and accused of murdering his crew, Carruthers becomes a prisoner aboard his own rescue ship, destined for a court-martial upon their return to Earth. Yet, Carruthers' defense is as chilling as it is implausible. He speaks of an unseen terror, a Martian entity that annihilated his crew during a monstrous sandstorm, leaving only him behind. His tale is a fantastical blend of horror and science fiction that the incredulous rescue team dismisses as a desperate attempt to evade justice. However, as the journey back to Earth commences, the crew is confronted with the horrifying realization that they are not alone. An insatiable alien predator lurks within the lower decks of the ship, confirming Carruthers' harrowing tale. As the extraterrestrial menace begins to hunt, turning the spacecraft into a claustrophobic death trap, the crew is thrust into a desperate struggle for survival. Doubt and fear permeate the ship as the truth of Carruthers' story unfolds, leaving them to grapple with the terror brought back from the stars.
