One of the classics in romantic comedies starring Katherine Hepburn and Cary Grant. 

Hilarity ensues in this 1930s classic as flighty heiress Susan (Katharine Hepburn) tries to get the attention of serious paleontologist David (Cary Grant), leading to wacky adventures involving a leopard named Baby. The chemistry between the two stars is electric and the plot is anything but predictable, making this one of the best romantic comedies ever!
