Up in the Air (1940)
Chosen from a list of public domain movies.
Fairly dull and nonsensical. A murder ostensibly kicks off plot proceedings but the film is much more interested in assorted people trying to get on a radio show.
Mantan Moreland (given only billing on that dvd cover but relegated to third in the film itself) gets most of the funny stuff though a lot of it is bug eyed 'Stepin Fetchit' style caricature that gave him a career for a long time but is generally viewed with contempt now.
