This movie's plot may be a bit thin, but who cares because the cast is great. The short version of the plot is that a worried mother recruits two men to find her runaway teenage son. How does she get them to agree to find him? She tells each of the men(obviously not thinking that they may run into each other while searching for the boy) that he is the father. This leads to a silly comic pairing.

There are all kinds of great things in this movie. Crystal and Williams are great together. Mel Gibson makes a cameo-- watch closely because you might not recognize him!! The band Sugar Ray is also in the movie. Cool things like that!

This may not satisfy a hunger for laugh out loud, slap on the knee kind of funny, but it's still funny, with a charming ending.

The teaming of Robin Williams and Billy Crystal provides some good moments, although at times Crystal seems to be too much of a straight man. Williams has plenty of scope to be...well, himself - which means that some sickly sentimentality is eventually allowed to creep in. In fact, the film is quite promising until the pair of wannabe dads make contact with their supposed offspring. The kid turns out to be such a snivelling loser that any sane person would disown him rather than try to save him from the conveniently cartoonish drug dealers he owes lots of money to. Junior is also infatuated with a girl who couldn't care less. When she finally tells him that he is boring, you find yourself shouting "Yes!" at the screen.

Even so, Williams and Crystal provide plenty of pleasant and undemanding entertainment along the way. But the film is so built around them that it wastes the talents of Julia Louis-Dreyfus and Natassia Kinski. Having said that, there is a nice uncredited cameo by Mel Gibson.

Not a bad film if you're looking for a nicely mindless comedy. But everyone involved has done much better work elsewhere.
