Movie Info

When lonesome astronomer Dr. Steve Mills (Dan Aykroyd) sees the extraordinarily beautiful but incredibly awkward Celeste (Kim Basinger) at a party, the last thing he would believe is that she is a space alien on a mission to do whatever it takes to save her planet, but he learns the truth when, despite her dubious intentions, he and Celeste decide to marry. Things get dangerous when Celeste's superior, whom she keeps in her magic handbag, decides to take care of matters himself.

Audience Reviews for My Stepmother Is an Alien

  • Jun 26, 2014
    A comedy that's out of this world, My Stepmother Is an Alien is an '80s cult classic. The story follows a scientist named Steven Mills who falls for an eccentric woman who's fascinated by his work at an astrological research center, but his daughter suspects that there's something not quite right about her. Starring Dan Aykroyd, Kim Basinger, Jon Lovitz, and Alyson Hannigan, the cast is quite impressive and does a good job at delivering the comedy; which is mostly a bunch of slapstick routines and fish-out-of-water jokes. And although the comedy may seem a bit rote, there's a certain sort of charm to it. My Stepmother Is an Alien is a little silly and formulaic, but it's also kind of fun.

    Ridiculous movie. It tries way too hard to be funny, and then wont stop trying until you're embarrassed to be watching. I like the actors, but they shouldn't have agreed to do this movie. It's much too goofy for its own good. I don't recommend it.

    An astrophysicist falls in love with a beautiful woman who is actually a disguised extraterrestrial in this high-concept comedy. Dan Aykroyd plays Steven Mills, a dedicated and harmlessly odd scientist researching ways to send radio signals to deep space. Unbeknownst to him, one of his experiments works better than expected, attracting the attention of an alien in need of help. She travels to Earth and poses as a human, assuming the name Celeste and the body of Kim Basinger. Celeste's lack of knowledge about humanity causes her to act bizarrely at times, but her odd behavior unexpectedly causes Mills to fall in love with her. The confused Celeste decides to play along for her planet's sake, but she finds her plan threatened by Mills' teenage daughter Jessie (Alyson Hannigan), who has become suspicious of Celeste after witnessing some odd behavior. The culture clash between Celeste's planet and Earth serves as an excuse for broad slapstick and sitcom-style humor, such as Celeste's fumbling efforts to enact the human ritual of "kissing."
