What's Up, Doc?

Like the classic screwball comedies of the 1930s, WHAT'S UP, DOC? centers on a madcap young woman (Barbra Streisand), Judy Maxwell, who disrupts the life of shy bespectacled professor Howard Bannister (Ryan O'Neal). Bannister arrives at a hotel to present his findings about ancient societies using rocks as primitive instruments. His prize rocks are in his plaid overnight bag, but as it happens, three identical bags arrive at the hotel at the same time -- one contains valuable jewels, another top secret government documents, and the last nothing more than a change of clothes. (Attempts by a spy to steal the bag with the documents and a thief to steal the bag with the jewels add to the storyline). Accompanied by his stuffy and overbearing fiancée, Eunice (Madeline Kahn), Bannister hopes to get a research grant from wealthy conference attendee Mr. Larabee. Judy, who is simply after a free meal, is drawn to Howard, and stays on to be near him. She impersonates Eunice at the opening dinner, utterly captivating Larabee. She then proceeds, as Howard says, to "bring havoc and chaos to everyone," including the destruction of a hotel room (and Howard's engagement), and a wildly funny car chase through the streets of San Francisco, before it all gets straightened out.
