Man.
This is a tough one for me. I grew up with classic movies, I love so many…If I listed them all, this post would be ridiculously long.
The Bing Crosby/Bob Hope Road series. Abbot and Costello vehicles, Mummy especially. Any flick with Sinatra. All Rodgers and Hammmerstein. White Christmas. All Harold Lloyd movies. Bathing Beauty. The East Side Kids shorts. The Topper series.High Society. New York, New York. Any Jimmy Stewart movie, especially Mr. Smith Goes to Washington. The Happiest Millionaire, actually all the old Disney movies. All the Clint Eastwood spaghetti westerns, esp. The Good, the Bad, and the Ugly.
There are more, but my heart is too full to keep typing. I love them all.
