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.

Critic Reviews for My Stepmother Is an Alien

All Critics (19) | Top Critics (2)

interesting as a time capsule of a rather conservative brand of '80s excess, and as a gender-switched companion piece to Earth Girls Are Easy. But on its own merits, it is what it is: a committee-written, dumb-assed mess, less amusing than alienating

December 13, 2021 | Full Review…

What we have here is a goofy comic performance by Kim Basinger, weighed down by a turgid script and a decision to use Dan Aykroyd mostly as a straight man. Too bad.

January 1, 2000 | Rating: 2/4 | Full Review…

The science in the film may be imaginary, the premise ridiculous, the escalation toward the conclusion absurdly exponential, yet it's difficult to not be charmed by it. In the parlance of the modern era, the film understood the assignment.

A limp comedy that could easily have been tagged E.T. The Extremely Tedious.

December 25, 2021 | Rating: 2/4 | Full Review…

Akroyd and Basinger give the film an infectious stroke of energy, and by the end we continue to smile even as we are exhausted under the weight of endless nonsense.

March 13, 2015 | Rating: 3/4 | Full Review…

Pretty dumb fantasy-sci-fi-comedy directed by Richard Benjamin.

Audience Reviews for My Stepmother Is an Alien

Yeah, it's silly, but it's cute and worth watching for Alyson Hannigan as the 13 year old daughter (and Seth Green as her date).

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.

Not one you'll feel bad about missing, but came across it on tv, easy watching, very forgettable.
