Initially, this was a project of Stanley Kubrick for MGM. He was so enthusiastic about the novel that he hired novelist Calder Willingham to write a screenplay with him. However, Production Code restrictions hindered the realization and the project never went into fruition. In July 2018, a complete screenplay for Burning Secret written by Kubrick and Willingham was found, so time will tell if their adaptation of the novel will come to light.
Final film of Jarmila Derkova.
MGM first announced this way back in 1964.
