It’s one of the oldest plots in show business: Hey, kids, let’s put on a show! In this 1936 movie, the cause they’re trying to benefit is a radio station that’s about to go bankrupt, and Jack Benny spearheads a “big broadcast” to save them. And what a broadcast: Benny Goodman and Gene Krupa play, George Burns and Gracie Allen play loosely disguised variations of themselves, and Benny himself ends up, as he should, on the business end of the mic. It’s a movie scrapbook of radio, filmed about a decade before TV took over. Ray Milland, seen here with Benny, co-stars.
