Holiday is coming out on DVD - and not in a box set. This 1938 George Cukor film, startting Katherine Hepburn, Cary Grant, and Edward Everett Horton comes out December 5. The studios released it a few months back in a Cary box set...with a bunch of movies I already owned.
If you haven't seen Holiday, I highly recommend it. It's classic screwball Cary - he does some physical comedy that would probably break a neck or a leg if you or I tried it. Lew Ayres is also a fun watch as the family drunk.
