Love in the Ring (German:Liebe im Ring) is a 1930 German sports film directed by Reinhold Schünzel and starring Max Schmeling, Renate Müller and Olga Tschechowa. Schmeling was a leading German boxer of the 1930s, and the film attempted to capitalise on this. Schmeling later appeared in another boxing-themed film in "Knockout" (1935).
If not for boxing, Schmeling would not have been in the boxing movies
Schmeling was only featured in those boxing movies because he was the top boxer in Germany in the 30s.
