Mollie (Kirstie Alley) is an accountant following her mother Rosie (Olympia Dukakis). She has an affair with her married client Albert (George Segal). She becomes pregnant with Mikey (Bruce Willis) while Albert keeps stringing her along. She catches Albert with his interior decorator Melissa. Cabbie James (John Travolta) drives her to the hospital. Later, he starts using her place to fake residence in Manhattan for his grandpa (Abe Vigoda) and also babysits Mikey. They fall in love but she resists.

The movie needs to cut out some of the beginning. Alley is forced to carry the whole thing by herself. It's not particularly funny. Much of it could be trimmed. It improves when Travolta shows up. Travolta and Alley have good comedic banter. The gimmick of talking babies have some fun moments. Willis is good and it's light fun. It's even funnier when the kid grows a little older and more adorable. There are some unevenness but overall it's fun likable comedy.

One of the great comedies of the past 30 years (and one that has fortunately stood the test of time),this turned TV star Kirstie Alley into a movie star and was a great comeback for John Travolta, his first hit since 1980's "Urban Cowboy". But honors really go to the delightfully funny and touching script and the voice participation of Bruce Willis whose entrance starts as a sperm fighting to get to the egg, and continuing as the voice of Alley's baby, the result of her affair with client George Segal who dumps her (and his wife) for an even younger woman.

When Alley's water breaks suddenly, she finds herself in Travolta's cab, and after a rollercoaster ride through Manhattan, baby Willis is born. Travolta and Alley become reluctant friends but Willis's constant demands for attention help turn this friendship into something more meaningful. Segal comes back to try to win Alley back, but it is obvious that he doesn't have the same chemistry with his son that Travolta does. Add in Olympia Dukakis as Alley's outspoken mother, and the makings for a modern masterpiece are also born.

You can't direct babies, and it's obvious that they filmed the baby scenes before writing Willis's dialog and added it in afterwards. For simply providing a voice over, Willis gets the bravos as baby Mikey. There's a very funny montage of Alley on various blind dates realizing how they'd be as stepfathers and slowly realizing that blue collar worker Travolta (who also teaches flight) is a match from God who hits it off with Mikey the moment he's born. Alley's fantasy of what Travolta would be like as a husband and father is also equally funny, and even if his character is rather crass, he's certainly more endearing than the stuffed shirts Alley goes out with.

While Alley's character is tough and no nonsense, Travolta here is sweet, perhaps a bit irresponsible, but definitely loving and perfect father material. This is a feminist movie that avoids misandry by making the male sympathetic and the female lead far from perfect. Veteran character actor Abe Vigoda is a delight as tr as Travolta's grandfather, a combination of Walter Matthau in "Kotch" and Art Carney in "Harry and Tonto". The looks that the various actors playing Mikey makes will have even the most stringent child haters grinning. Dukakis and Louis Heckerling (as Alley's father) are a younger version of Mary Wickes and Conrad Bain from "Postcards From the Edge".

What easily could have been a decent but generic comedy really stands the test of time because of its originality and its big heart where the heroine has the perfect guy right in front of her from nearly the beginning but doesn't realize it. This is one film where I actually looked forward to the sequel. A casting change as we see here at the end changed but does get a huge laugh with the identity of the voice a perfect way to end the movie.

John Travolta is very charming in this film.The chemistry between John and Kristie is fabulous. They both look great together. The director captures the best expressions of the baby.. Bruce Willis does well with the voice over. A nice feel good film
