20. Listen, Darling (1938)
A very silly and frankly odd musical, although perhaps not quite odd enough to qualify for cult status. Judy Garland plays a girl called Pinkie who is worried about her widowed mother, played by Mary Astor – and believes she needs to get remarried to a nice man. So with her pal Buzz (played by the renowned former child actor Freddie Bartholomew, of David Copperfield and Little Lord Fauntleroy fame), she in effect kidnaps her bemused but indulgent mother in a trailer and tours around the country looking for a likely stepdad candidate – and hits on Walter Pidgeon. As so often, Garland steals it with a standout song, this one being Zing! Went the Strings of My Heart.
