There is clearly a market for this type of screwball comedy it just doesn't do anything for me. Nothing is supposed to be believable and I frankly thought that O'Neal was horrible. I do like that they address that ridicuous line from Love Story though. I'm usually a Barbra Streisand fan, but I feel this was totally beneath her. I'm sure this type of comedy appeals to other and really you're just going to have a take a chance and see if this tickles your fancy. I still love Barbra.

Great older movie. Madelaine Kahn is fabulous. Constant funny situations and chase scenes.

This movie is fantastic and if you are soured on all the unnecessary violence and sex in many Hollywood films, this older movie will cheer you up. It is delightfully silly and full of wonderful lines.

This priceless movie with all its gags, bits and skillfully timed stunts and visuals is absolutely hilarious!!

Coupling the extremely funny and beautiful, Madeline Kahn with Ryan O'Neal, the geeky, handsome, straight man was "pure genius" and then there's Barbra Streisand and her character ...Superb, charming, beautiful, and devilishly impulsive!

I laugh just thinking about this union of character's... perfect!!!

All actors and their characters are played perfectly throughout - just like a good recipe take out one ingredient and it just wouldn't be the same.

The tangled mess that is this movies story line starts when Streisand and O'Neal's character's meet in a store while he's looking for aspirin adding along the way a couple of side story's that seamlessly come together over suitcases and what's within them, yes I said, "Suitcases!!" - all are the same style and make... then all hell breaks loose!!

"WOW!! Too funny and wonderfully entertaining!!!"

This is for me one of the best comedy's of its time/era!!! You've got to watch this movie at least once if not many times.

I first saw this movie when I was a kid. But now that it is available on DVD, watching it again after 30 years sure brings back memories of the way comedies were done in the early 70s. Striesand was at her usual self, a good role for her and she went on to do better in THE MAIN EVENT pairing up again with O' Neal. Just wondering how the two felt about each other when they were cast again in opposite roles...But the climax in What's Up Doc is the judge in the court turns up to be Streisand's father. That's a good one. Peter, the director, must be given the credit to come up with the idea. I bought two discs, and the other would be given to a friend who is celebrating his birthday soon. When the movie was made, he had turned two. So he didn't have the chance to see it. Thanks to Warner Bros for putting the movie available on DVD.
