Robin Williams does an older version of "Tootsie" in "Mrs. Doubtfire," which blatantly steals a number of very specific elements from the classic Dustin Hoffman comedy of more than a decade ago.

There's no question that this film was tailored to Williams' talent for improvisation, and there are several scenes where director Chris Columbus obviously just lets his cameras roll as Williams does his wacky thing.

When that happens, "Mrs. Doubtfire" is very funny.

And as with "Tootsie," there are also some serious themes addressed here. But unlike "Tootsie," "Mrs. Doubtfire" tends to bog down during those moments — and there are far too many of them.

And despite the PG-13 rating — and the ads, which scream "family movie!" — much of the language is too blue for children.

Williams plays a San Francisco actor who has a talent for voice work, but his reputation for being difficult causes him to be perpetually unemployed. His wife (Sally Field) is a successful designer and they have three adorable kids.

But at home, Williams is a bigger kid than the kids, and Field is tired of being the villain who has to bring order to their home. So, when he brings a menagerie — including a pony — right into their house one afternoon for a birthday party, Field loses it and files for divorce.

Williams is so attached to his children that a court ruling that he can see them only on weekends is devastating, so when Field advertises for a housekeeper, he comes up with a bizarre scheme to be able to see them every day.

Williams approaches his brother (Harvey Fierstein), a gay makeup artist, for a matronly makeover. Then, adopting a vague Scottish brogue, Williams is transformed into a virtual Mary Poppins, albeit the size of a football player.

Ingratiating himself to the family in this new guise, and taking care of the household chores for the first time, Williams becomes more responsible and domesticated, applying his newfound talents to his own bachelor pad as well. And, of course, he gradually becomes a better person as a woman than he ever was as a man.
