Bringing Up Baby is a 1938 screwball comedy directed by Howard Hawks and starring Katharine Hepburn and Cary Grant. It tells the story of a scientist winding up in various predicaments involving a woman with a unique sense of logic and a leopard named Baby. The supporting cast includes Charles Ruggles, Barry Fitzgerald, Walter Catlett, and May Robson.

Adapted by Dudley Nichols and Hagar Wilde from a story by Hagar Wilde, Bringing Up Baby was an infamous box office catastrophe, causing Hawks to be fired from his next RKO film (Gunga Din, also starring Cary Grant) and forcing Hepburn to buy out her contract. As time went on, however, the movie gained more and more attention and is now revered as a sophisticated classic decades ahead of its time, and it continues to generate revenue for Hepburn's estate.

Bringing Up Baby is number ninety-seven on AFI's 100 Years...100 Movies, number fourteen on its 100 Years... 100 Laughs, and number fifty-one on its 100 Years... 100 Passions. In 1990, it was selected for preservation in the National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant", going on the second year that the registry started preserving films. Entertainment Weekly also voted the film number twenty-four on its list of the greatest films. In 2000, readers of Total Film magazine voted it the forty-seventh greatest comedy film of all time. It is also consistently on the Internet Movie Database's list of top 250 films.

The 1987 movie Who's That Girl? starring Madonna is loosely based on this film, as is the 1972 Barbra Streisand classic What's Up, Doc?, directed by Peter Bogdanovich.

David Huxley is waiting to get a bone he needs for his museum collection. Through a series of strange circumstances, he meets Susan Vance, and the duo have a series of misadventures which include a leopard called Baby. Written by Liza Esser

In this screwball comedy, heiress Susan is determined to catch a stuffy paleontologist and uses her pet leopard, Baby, to help get his attention. The elements of this farce include a yappy terrier who steals and buries an irreplaceable fossilized bone, a pompous big game hunter, a rich old aunt, a jealous fiancée, and a case of mistaken identity involving a second, and vicious, leopard. Written by Fiona Kelleghan

When Susan Vance (Katharine Hepburn), a scatterbrained young woman, takes a shine to Dr. David Huxley (Cary Grant), a sober palaeontologist, mayhem ensues. Dr. Huxley, engaged to be married and intensely interested in the arrival of the brontosaurus bone required to complete his project at the museum, is inextricably bound up with Susan's escapades when she finds herself responsible for Baby, a tame leopard shipped to her New York apartment and intended for Susan's aunt in Connecticut. The plot thickens when George the Terrier steals the priceless bone and buries it, Baby escapes, and an untamed leopard escapes from a circus convoy (resulting in a twist on the mistaken identity ploy). Will Susan's love for David be reciprocated? Will David get his bone back? Will Baby be brought up - or brought down? Written by OneSuch
