so it looks like we're going through and up and through and over to create this illusion that we're going forward when we're going nowhere. Then the pushing and pulling of the things so that the bike is up and down, and we can get the 'Whoaaaa' effects. That was great." BMX riders Robert Cardoza, Greg Maes, David Lee, Grant Meyers, Chris Taylor, Duke Britton, Steve Williby and Bob Haro served as stunt doubles for the scene. Music Spielberg's regular collaborator John Williams, who composed the film's musical score, described the challenge of creating one that would generate sympathy for such an odd-looking creature. As with their previous collaborations, Spielberg liked every theme Williams composed and had it included. Spielberg loved the music for the final chase so much that he edited the sequence to suit it. Williams took a modernist approach, especially with his use of polytonality, which refers to the sound of two different keys played simultaneously.

An audiobook companion album featuring Williams' score, produced by Quincy Jones and narrated by Michael Jackson, was released on November 15, 1982, the same month as Jackson's acclaimed sixth studio album Thriller.

Spielberg denied this, stating "I was a kid in high school when his script was circulating in Hollywood." Star Weekend Magazine disputed Spielberg's claim, pointing out that he had graduated from high school in 1965 and began his career as a director in Hollywood in 1969. The Times of India noted that E.T. and Close Encounters of the Third Kind (1977) had "remarkable parallels" with The Alien, including the physical nature of the alien. In his screenplay, which Ray wrote entirely in English, he described the alien as "a cross between a gnome and a famished refugee
