Let a fantasy be a fantasy. All space adventure movies are fantasies. Some lay claim to be realistic but in fact they are pseudo-realistic and may implant false ideas in peoples mind about the possibilities of space travel and extraterrestial colonization.
Ok, H.-G, I'm fine with that.
When you mentioned this Mars movie with Val Kilmer (with I like very much, he also was in "The Saint", the Cold Fusion Movie

Elon Musk's / SpaceX vision of colonisation of Mars and then using Mars as a base to go the Asteroid Belt, starting in 2022 (I know, Elon's milestone s are "ambitiously" are in the timewindow that I hope to be still alive.
BTW: Have you seen the TV-Series "The Expanse" ?
