Space Marines is a 1996 American science fiction film directed by John Weidner and written by Bob Moreland.

[2] The film received a mixed review in The Washington Post, writing it was very "silly but also cheerfully watchable".

[3] Video Movie Guide stated: "Fans of old sci-fi serials should love this retro" production, where "Billy Wirth shines as the gleefully maniacal villain" and conceded that "Moreland's script has the sense not to take itself too seriously.

"[4] The film was also described as a "(c)heesy cable thriller (with) intergalactic marines",[5] in which Weidner's direction did not "always succeed in making derring-do look believable".

"[2] "The effects aren't all bad but otherwise this is a standard direct to video fare with a dull script peppered with the usual violence, explosions and gunfire", wrote Howard Maxford in The A-Z of science fiction & fantasy films.
