An astrophysicist falls in love with a beautiful woman who is actually a disguised extraterrestrial in this high-concept comedy.

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." ~ Judd Blaise, Rovi

    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, th... read moree 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.

    A very funny movie. I wish Dan Aykroyd had done more movies like this. The story was entertaining. Trivia: The daughter was played by Allison Hannigan and her boyfriend was played by Seth Green. The two would later play a couple in the Buffy tv series.

    Witless low concept comedy, only of interest for Buffy fans for the appearance of Alyson Hannigan and Seth Green in early roles.

    Kim Basinger's no comedieene, but there are some nice touches in this tale of a gorgeous alien getting hitched to Dan Aykroyd so that she can save her planet from his invention and, along the way, learn all about love, sex and sneezing.

    I saw this on the Disney Channel years ago and it was a bit disturbing.
