I second the above movie recs, especially The Philadelphia Story, one of my favorites. The interplay between Cary Grant, Katherine Hepburn and Jimmy Stewart is so delightful. If you liked Singin' in the Rain, you should also watch An American in Paris, another brilliant Gene Kelly movie. I love Bette Davis and recommend All About Eve, Now, Voyager and Mr. Skeffington and anything else she's in. Also, anything with Bogart & Bacall is worth seeing - my favorite of theirs is To Have & Have Not. Cary Grant movies I love: Charade, To Catch a Thief, Notorious. OMG, I could go on & on, I love old movies!
