Live ammunition was used in the film - in interviews, actor Aleksey Kravchenko has described actual bullets passing some 10 centimeters above his head.
The director planned to have Aleksey Kravchenko hypnotized by a psychotherapist during the most dreadful and violent scenes so that they wouldn't affect his young mind. However Kravchenko turned out not to be susceptible to hypnosis and had to pretend all the way.
The Einsatzgruppe unit that attacks Perekhody is known as the 15th Einsatzkommando but there was a actually no unit with that designation during World War II.

This movie's title is derived from The Bible's New Testament. It is from Chapter 6 in the Book of Revelation (aka The Apocalypse of John aka The Revelation of St John the Divine aka The Revelation of St John). It reads: "And when he had opened the fourth seal, I heard the voice of the fourth beast say, Come and see. And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth."
The film's literal English translation from the Russian wording "Idi i smotri" is "Go and look" but the film is more commonly known in English as "Come and See" instead.
