This was two-time Best Actress Oscar winner Luise Rainer's first theatrical movie since Hostages (1943).
This was not the first time Director Károly Makk made successful use of a distinguished elderly actress. In his movie Love (1971), Makk used Lili Darvas, who, like Luise Rainer, was a star of the Max Reinhardt theater troupe. Also like Rainer, Darvas married a famous playwright, Ferenc Molnar. (Rainer was married for a while to Clifford Odets.)
