* DuelingMovies: The original title of this film was, simply, ''Mars''. But the release of ''Film/MissionToMars'' in the same year required a name change.
* HostilityOnTheSet: Creator/ValKilmer and Tom Sizemore began feuding during production. According to reports, it all began when Kilmer got annoyed about a fancy exercise machine that Sizemore wanted shipped from England to the set in Australia. Eventually the two hated each other so much, Kilmer would not come out of his trailer if Sizemore was on the set. Many of their scenes together were filmed over the shoulders of photo doubles. Kilmer reportedly refused to say Sizemore's character's name, saying instead "Hey, you!" At one point, they got into a confrontation that escalated into them throwing weights at each other until Sizemore knocked out Kilmer with a punch to the chest. (At a crewmember's request, he avoided Kilmer's face). The two have never worked together again.
