“The Curse of the Snake Valley” was a box-office success: about 1 million viewers saw the film in Poland and as many as 25 million in the USSR.
Marek Piestrak’s film became a classic work of art primarily thanks to its faults. Today, it appears on almost every list of "movies so bad that they’re good" and is still a source of great entertainment.
The name of the award currently given to the worst Polish films comes from the title "The Curse of the Snake Valley".
The screenplay is based on the story by Robert Stratton "The Hobby of Dr. Traven”. This was the pseudonym of Wieslaw Górnicki, known primarily as the author of the famous speech delivered by Wojciech Jaruzelski, in connection with the announcement of martial law.
