David Huxley (Cary Grant) is a straightlaced paleontologist who wants nothing more than to complete his assembly of a brontosaurus skeleton & to marry his assistant, Miss Swallow. David's wishes are on the verge of coming true when he meets the madcap heiress, Susan Vance (Katharine Hepburn). What ensues is a hilarious adventure. In the spirit of Shakespeare's A Midsummer Night's Dream, David & Susan tramp across the countryside searching for leopards, a dog, & a dinosaur bone.
A wonderfully goofy movie directed by Howard Hawks and starring Cary Grant as an absent-minded paleontologist (David Huxley) trying to complete a Brontosaurus skeleton (he needs an “intercostal clavicle” – whatever that is!) and the beautiful young Katherine Hepburn as a loony heiress (Susan Vance) with a pet leopard named “Baby.” Their zany escapades involve Susan’s dog “George” who steals the dinosaur bone and a confusion of identify between “Baby” and another not-so-tame leopard that’s escaped from a local circus. At the end of the movie, Susan arrives at the museum with the “intercostal clavicle” that “George” has returned as well as a promise of a million dollars for the museum. Huxley and Vance confess their love to each atop a ladder which falls and collapses the Brontosaurus
