Holiday

1938 George Cukor comedy starring Cary Grant and Katherine Hepburn was a follow-up to the success Grant and Hepburn had with Bringing Up Baby.

Free-thinking, happy-go-lucky Grant is enaged to an heiress but when he begins to question the meaning of his life he finds he has much more in common with her spirited sister (Hepburn).

Smart writing, great cast, and very funny screwball comedy.

Bringing Up Baby

Howard Hawks directed this comedy starring Cary Grant and Katharine Hepburn.

One of the best movie comedies ever.

Grant plays a nerdy professor who is drawn into the life of a wacky heiress who changes him forever. A totally screwball comedy if there ever was one.

Grant and Hepburn are wonderful together. Lots of abusrd situations but it all works. The stars shine in this one.

Remade (sort of) as "What's Up Doc?" with Ryan O'Neal and Barbara Streisand.

Don't miss this one.
