Alien Covenant Poster, multiple influences just like Dan O’Bannon’s first draft script for Alien.
“I didn’t steal from anybody,” he explained, “I stole from everybody!” The works most commonly cited and acknowledged by O’Bannon as key influences on Alien include 1956’s Forbidden Planet and the aforementioned It! The Terror From Beyond Space, released in 1958. Literary influences include a wealth of Weird Science and Weird Fantasy comic strips as well as the collective works of HP Lovecraft. Other possible sources include Planet of the Vampires (Dan and Ridley claimed not to have seen it) and A.E. van Vogt’s novel The Voyage of the Space Beagle (Dan never read it.)Alien Series WordPress
Paradise Lost is about the creation of Adam and Eve and how they lost their place in the Garden of Eden/Paradise. In the first pages of Genesis, it’s the same story but expanded by Milton into a long detailed poem.
Alien Covenant’s working script name was titled Alien: Paradise Lost
Hell and Heaven is described as places with similar geographical properties as Earth, containing mountains, rivers, valleys and seas. But Hell is described as the worst of nature, Milton emphasizes the awful, inescapable smells of Hell, the raging “perpetual storms,” the rivers with their “waves of torrent fire.”
His description attempts to answer why famine, flood, and fire that kill and destroy mankind. Milton‘s descriptions show these are not works of God, but by nature perverted, caused by the creation of Hell and evil after Satan’s Fall.
Just as David’s Hell was created after he dropped the Black Ooze onto the Engineer planet.
The Gates of Hell is a monumental sculptural group work by French artist Auguste Rodin, depicting a scene from the Inferno, the first section of Dante Alighieri’s The Divine Comedy.
It looks like the poster was made from an amalgamation of inspirations relating to the stories which inspired Alien: Covenant.
Many items can be seen in this poster, Engineers, Xenomorphs & Facehuggers are the most obvious ones.
Others have speculated we can see the crest of a Xenomorph Queen, the Hammerpede and possibly the inside of the Hive.
The Gates of Hell is inspired by another work of Lorenzo Ghiberti, although Auguste Rodin’s gates are more well known, it is only a copy. This sort of theme is carried through both Prometheus and Alien: Covenant. Art pieces and music referenced have been riffed on to create similar works. I think this plays strongly into the theme of creation and origin, such as who created the Xenomorph and does it matter?
