Movie Info

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."more

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.

Another film for Aykroyd in 88 only this time in my humble opinion its a weak one with a very silly B-movie type premise and a poor performance from the over hyped (at the time) Basinger. Even Aykroyd can't save this very average film with his usual zany comedy and fast quips, the effects are really dated and I don't think event that good for its time whilst the comedy is lacking, all the film does really is show how poor an actress Basinger is. Look out for a very young Seth Green and of course Alyson Hannigan.
