After the movie was released, screenwriter Joe Eszterhas's own father, Istvan Eszterhas, was accused of war crimes in Hungary for printing anti-Semitic editorials and even organizing a book burning.
Both Kirk Douglas and Walter Matthau wanted to play the father (Michael Laszlo) and were in contact with director Costa-Gavras. Costa-Gavras also considered Marlon Brando for the part. Instead, he picked Armin Mueller-Stahl, who a couple of years earlier had said he would love to work with him after seeing his movie, Missing, at the theater.
Joe Eszterhas wrote the screenplay with Jane Fonda in mind to play the female lead. Both Eszterhas and producer Irwin Winkler wanted to cast Fonda but director Costa-Gavras thought that she was too old for the part and cast Jessica Lange instead. Fonda was paid $1.25m in compensation for losing the part.
