- Father of producer Mario Kassar, who was executive producer of the Sylvester Stallone alpine action film Cliffhanger (1993). The senior Kassar died during production of that movie, so the film was dedicated to his memory, as well as to that of Wolfgang Güllich, Stallone's climbing stunt double, who died in a car accident in Germany three days after production ended.
