One of my favorite comedies from the 1940s Is The Bachelor and the Bobby-Soxer. This little gem (with an Academy Award-winning screenplay by Sidney Sheldon) stars Cary Grant as the bachelor, Shirley Temple as the bobby-soxer, and Myrna Loy as a judge who happens to be Shirley’s big sister. The plot is simple. Grant gives a speech at Shirley’s high school, and Shirley becomes infatuated with him. Grant has to fight her off even as her suspicious sister brings the arm of the law down upon him. I’ll bet you can guess who Grant ends up romancing. It’s all great fun, especially a scene where Grant takes on the persona of a teenager for a little bit of payback.
