Many Zodiac researchers believe the Zodiac Killer was influenced by the movies, so I wondered whether the Zodiac Killer borrowed the movie title "Rampage" when writing his threats to "kill a dozen people over the weekend", stating "If you do not print this cipher, I will go on a kill rampage Fry night. This will last the whole weekend, I will cruse around killing people who are alone at night untill Sun Night or untill I kill a dozen people".
Additionally, newspaper advertisements of the movie in 1963 carried the wording "Big, Bold, Bob Mitchum is on a Rampage", missing only the word "kill" that was added by the Zodiac The movie's opening credits, movie poster and original Warner Brothers press book cover contained "go on the rampage", "the most dangerous game of all" and the "crosshairs", which were all heavily used by the Zodiac Killer on July 31st 1969. The phrases "go on the rampage" and "the most dangerous game of all" were also featured in the newspapers throughout America in 1963. Here are three examples.
The 1963 Rampage movie was based upon a novel first published in 1961 by Alan Caillou, released as a 1963 paperback version with the following wording on the front cover: "A big novel of two white hunters who battle to possess a beautiful woman as they track the jungle for the most dangerous game of all" (see large image above). The rear cover of the 1962 hardbook version read "A killer leopard - and an even more dangerous woman. This is a leopard, Harry. He'll keep close to us just in case he can make a kill. It's the only other animal that kills for the fun of it", followed by "But the leopard - for the sheer enjoyment of killing, just for the pleasure of it. He kills because he likes it. There's only one other animal that does that, Harry. And that's man". The Zodiac Killer began his 408 cipher with "I like killing people because it is so much fun. It is more fun than killing wild game in the forest because man is the most dangerous animal of all".
Many newspaper articles featured large advertisements for the Rampage movie, carrying headline statements such as "They lived, loved and fought by the code of the jungle" [1] and "His code was to snare everything" [2]. Therefore, it is quite ironical that the Zodiac Killer would place key phrases from the Rampage movie poster and original Warner Brothers press book within his code, detailing murder. It should be noted that the original Warner Brothers press book also contained the phrase "They lived and loved by the code of the jungle". Could this possibly have influenced the Zodiac Killer to encipher his message on July 31st 1969?
This movie may have featured in the Zodiac Killer's sequel communication on December 20th 1969, the first anniversary of the murders of David Faraday and Betty Lou Jensen, which began his "Big Hunt". The movie "The 10th Victim" was released into US cinemas on December 20th 1965. The only time the Zodiac Killer wrote a victim count in tandem with the word victim (victom) was when he mailed the Melvin Belli letter on December 20th 1969, stating he was in danger of losing control and claiming his "tenth victim". We have a movie based on "The Most Dangerous Game" released on December 20th 1965 about hunting victims, followed by the Benicia murders on December 20th 1968, followed by the Melvin Belli letter on December 20th 1969, threatening a ninth and "tenth victim".
"The 10th Victim" and "The Big Hunt" spoke of "control", just like the Melvin Belli letter. Early in the movie, the "announcer" laid out the benefits of "The Big Hunt" over the tannoy system, stating "If you would do away with the terrible wars of the masses, become a member of the Big Hunt. Make your murders legal. Only the Big Hunt can give the world a feeling of true security. An enemy a day keeps the doctor away. Why have birth control when you can have death control. Live dangerously, but within the law. If you are suicidal, the Big Hunt has a special place for you". The Zodiac Killer pleaded "The one thing I ask of you is this, please help me. I cannot reach out for help because of this thing in me wont let me. I am finding it extreamly difficult to hold it in check. I am afraid I will loose control again and take my nineth & possibly tenth victom. Please help me I can not remain in control for much longer".
Just like the "Rampage" movie, "The 10th Victim" had the crosshairs present within the movie title, as shown in the original 1965 poster.on the right.
Therefore, we have two movies in 1963 and 1965 about hunting, both more contemporary to the Zodiac murders, carrying the elements of "go on the rampage" (go on a kill rampage), "the most dangerous game of all" (the most dangerous animal of all), "a dozen men" (a dozen people), "the movie phrase in the code", the "crosshairs" in both movie titles, "The 10th Victim" (tenth victim), "The Big Hunt and control" and the date of December 20th running through 1965, 1968 and 1969. So was "The Most Dangerous Game" the primary inspiration for the July 31st 1969 letters?
ADDITIONAL INFORMATION
Abbot realizes he's in danger of losing his "most prized" trophy, as Anna becomes the key "prize" for both game hunters in the Rampage movie (see below). The Zodiac Killer would mail another cryptogram of 148 characters around May 1971, which carried the phrase "man is the most prized game" in the accompanying letter. Therefore, we have two communications containing the phrases "man is the most dangerous animal of all" (in the 408 cipher) and "man is the most prized game" (with the 148 cipher), both of which have relevance to the film. The Bay Area murderer would also mimic the crosshairs from the opening sequence of the Rampage movie at the foot of the 1971 letter, dispensing with the overhanging lines. See here.
