On the Sunny Side(1962)

The story of the steel melter Martin Hoff, whose factory delegates him to a drama school, corresponds to the real life of the actor Manfred Krug. Like his (film) hero, Krug works as a steel melter, does artwork, sings and acts, and is sent to drama school. Like his hero, who behaves anarchically and conspicuously, Krug is soon expelled from school.
