Inseminoid

Inseminoid (1981) is a British sci-fi horror film you can watch online on iFILM, directed by Norman J. Warren. An archaeological crew digs too deep on a remote planet and wakes something that should have stayed buried.

Exploring the catacombs of a dead civilization, the team uncovers strange crystals that drive one member insane. Then an alien attacks and impregnates Sandy (Jennifer Ashley). The pregnancy races ahead, her mind breaks, and she begins hunting the rest of the base one body at a time. Stephanie Beacham, Victoria Tennant and Judy Geeson round out the doomed crew.

Made in the wake of Alien but rougher and far cheaper, it became a notorious title from Britain's "video nasty" years — panned by critics, cherished by gore fans. Claustrophobic, mean, and not built for comfort. Stream Inseminoid (1981) online on iFILM.
