Flying Down To Rio(1933)
The Yankee Clippers get an engagement in Rio de Janeiro, after they are fired from a Miami hotel because band leader Roger Bond has flirted with Brazilian guest Belinha de Rezende. Roger gets Belinha to accompany him to Rio in his private plane. En route, the two land on a moonlit beach for repairs and have a romantic interlude. However, Belinha is already engaged to Roger's best friend, Júlio Ribeiro, who is also in Rio.
This looks like a re-release trailer for the movie.
