Seksmisja (1984)
1 plot hole - chronological order
Directed by: Juliusz Machulski
Starring: Jerzy Stuhr, Boguslawa Pawelec, Bozena Stryjkowna, Olgierd Lukaszewicz
Visible crew/equipment: When Max, Albert and Lamia exit the underground and walk inside the tent with painted false landscape, there are regular rows of studio lights visible reflected in their helmets. They would immediately recognize that it's not a real world if the lights were there.
Trivia: As Lamia command two women to find Eldest Granny for her, there's a pan of computer screen with names of old women on it, and you can see Ella Kwinto in one line. Kwinto was a surname of main character in "Va Banque", another fine movie directed by Julius Machulski.
