Desk Set (1957): badass librarian Hepburn meets computer guy Spencer Tracy who is looking to automate her job. She proves that librarians are more efficient than his computer, which kinda explodes, and they fall in love. As a librarian I obviously love this one.

Bringing Up Baby (1938): Hepburn acquires a leopard and bullies paleontologist Cary Grant into helping her with it. Her dog steals his prized fossil and they chase both after fossil and leopard. At one point Grant dons a fluffy bathrobe and exclaims "I just went gay all of a sudden!"

The Philadelphia Story (1940): my favorite movie of all time. Stars Hepburn, Cary Grant, *and* Jimmy Stewart as divorced heiress Hepburn prepares to remarry. Grant is her ex-husband and Stewart is a reporter sent to cover the wedding. Hijinx ensue; I could probably recite the whole script.

Christopher Strong (1933): Katharine plays a pilot who falls in love with someone else's gross husband. The costumes were excellent and the director was a lady (Dorothy Azner). That's about all it's got going for it besides Hepburn.

When I get older I plan to scare small children by teaching them about HitClips.
