Toboggan (1934)

Toboggan, the 1934 Henri Decoin French boxing sports romantic love triangle melodrama (about a washed up boxer who makes a comeback for a sexy dancer, but she is two-timing him, and she brings her boyfriend into the arena during the climactic boxing match) starring Georges Carpentier (real life heavyweight boxing champion), Arlette Marchal, Paul Amiot, John Anderson, and Raymond Cordy. Note that because Carpentier was a real life boxer, he naturally was able to do his own boxing scenes, and the producer of the movie interwove footage of Carpentier from his actual matches into the film.

Unfortunately the movie Toboggan is not yet available on HBO Max.
