Forbidden Planet pioneered several aspects of science fiction cinema. It was the first science fiction film to depict humans traveling in a faster-than-light starship of their own creation. It was also the first to be set entirely on anotherplanet in interstellar space, far away from Earth. The Robby the Robot character is one of the first film robots that was more than just a mechanical "tin can" on legs; Robby displays a distinct personality and is an integral supporting character in the film.Outside science fiction, the film was groundbreaking as the first of any genre to use an entirely electronic musical score, courtesy ofBebe and Louis Barron.
Forbidden Planet's effects team was nominated for the Academy Award for Best Visual Effects at the 29th Academy Awards. In 2013, the picture was entered into the Library of Congress' National Film Registry, being deemed "culturally, historically,or aesthetically significant". Tony Magistrale describes it as one of the best examples of early techno-horror.
