Looked at "Flying Down to Rio" (1933) last night. Nostalgia plus! One of the first musicals with great choreography.
A weird number features showgirls doing their thing on the wings of those tincan planes of the time, the planes flying in formation.
A feature was a spectacular dance sequence based on the "Carioca."
Fred Astaire and Ginger Rodgers were in supporting roles to Dolores del Rio and Gene Raymond, a break-in for them and sort of a swansong for Raymond and del Rio (she couldn't lose her Latin accent).
Great fun!
