* DuelingMovies: ''[[Film/RedPlanet Red Planet]]'' was released in the same year, with a little better [[ShownTheirWork polish]] in the science of the film.
* ScienceMarchesOn: [[spoiler:The Face on Mars at Cydonia was shown in later, less blurry, photos to actually have almost no resemblance to a human face whatsoever.]]
* Some of the props and part of the spaceship set are now on the ''Mission: SPACE'' attraction at EPCOT Center in Florida (with the attraction's opening film starring Gary Sinise, to boot).
