The Red Line is characterized by a brilliant cinematography and set design, but it encountered problems in connection with the proper dress code of the actresses and has been shelved after its screening at the first Fajr Film Festival. (One of the main problems was the appearance of Ali Mahzoon and Iren (Irene Zazians, the sexy star of pre revolutionary films) who starred as the parents of the girl.
In the version of the film that was shown later at the festival, their roles had been replaced by two other actors and they had become two of the guests. Also in the original print, the parents were from an aristocrat family who like the new husband, but in the final version they were changed to a poor family who were strongly against the wedding of their daughter with this man.
Finally, the biggest problem was Saeed Rad himself; SAVAK agents were supposed to be portrayed as ugly men from rich families. Saeed Rad was neither. Last but not least, the brother of Laleh, was originally a leftist guerrilla fighter who was later changed to a religious fighter.)
