Species Trilogy (1995) (4-Disc Set)

SPECIES: A genetically engineered, shape-shifting creature with extraterrestrial intelligence adopts the form of a beautiful woman to mate with humans and unleash a brood of offspring that will destroy mankind. A team of experts must band together to stop her--it--from accomplishing its diabolical mission. Special editions contain behind-the-scenes footage with creature creator H.R. Giger.

SPECIES 2: Sil, the sex-crazed alien life form from the predecessor "Species" is now a clone named Eve (Henstridge). Eve is the acting subject of governmental experiments until a trio of astronauts returns from a trip to Mars and one starts behaving rather strangely. Astronaut Patrick Ross (Lazard) begins to act eerily similar to Sil in that sexual predator sort of way that Henstridge made so endearing in SPECIES.

SPECIES 3: Returning for a third bite of the SPECIES cherry, director Brad Turner replaces the curvacious Eve (Natasha Henstridge, who makes a brief appearance) with her daughter and fellow hottie Sara (Sunny Mabrey). The battle between mankind and the human-alien lifeforms has gathered pace since the last frenetic round of SPECIES action, with the humans gaining a slight upper hand. But the emergence of Sara soon gives the aliens a vital boost to their efforts, with the deviously seductive hybrid heading to earth in order to repopulate it by reproducing as much as possible! Her incredible sex drive allows her to carry out the taxing mission, but a huge human military presence is gathering, aiming to put Sara and her cohorts out of action for good.
