The “Men Are from Mars, Women Are from Venus” trend takes a weird new twist in the 2004 Canadian shocker “Decoys” (8 p.m. today, Sci Fi). Equal parts “Species” (6 p.m. today, Sci Fi) and “Porky’s,” the film explores this mind-boggling question: What if a group of sexy sorority sisters were really extraterrestrial beings out to seduce randy college freshman and freeze them to death with their tentacles? If you try real hard you can find some kind of “Stepford Wives”-type satire here, but for the most part the movie argues the point that the mere whiff of sex, even sex with frigid aliens, turns young men into blithering idiots.

• Not quite up for monstrous vixens? How about lonely boy robots? Haley Joel Osment stars in the 2001 sci-fi drama “Artificial Intelligence” (7 p.m. today, ABC) as a Pinocchio-like cyborg playmate out to find his real mother. Director Steven Spielberg completed this project based on a script commissioned by the late Stanley Kubrick.

Film critic Leonard Maltin calls the film a “curious and uncomfortable hybrid” of the two directors’ sensibilities. Like many contemporary films, “AI” drags on far too long.

• Can healthy eating habits be taught? And will children pay attention if you try to instruct them? In the Nick News special “Look Before You Eat” (7:30 p.m. Sunday, Nickelodeon), host Linda Ellerbee says that “if kids learn how to make healthy choices now, they’ll eat healthy for the rest of their lives.” To spice things up, she’s invited chef Emeril Lagasse to keep the kids awake with a “bang” or two and “kick it up a notch” when they start to nod off from sugar deprivation.
