abstract:Worlds in Collision is a book written by Immanuel Velikovsky and first published April 3, 1950. The book postulated that around the 15th century BCE, Venus was ejected from Jupiter as a comet or comet-like object, and passed near Earth (an actual collision is not mentioned).
What Cronenberg and his screenwriter, Steve Knight, want to engineer is a collision between worlds that have nothing no social habits or moral norms in common.
