Originally shown as a TV miniseries in 4 episodes. A slightly longer theatrical version was released abroad after the TV premiere.
For the UK release, 5 seconds were cut from the fourth episode ("The Living Dead") where Rigmor shoots rats with a pistol. The footage was cut under the Cinematograph Films (Animals) Act of 1937, which forbids the depiction of cruelty to animals.
The series was released in some territories in a five-episode version, with each episode running approximately 50 minutes. This is the version available on video in the UK and Canada.
