The executive producer of Xanadu, Lee Kramer, had a dream. A dream for a rocking Silver Surfer movie that heralded the character's entrance with 100 electric guitars along with a maddening chant. Alas that vision (which started back in the 1980s) never came to pass.
Movies.com has a quote from Kramer, pulled from Sean Howe's forthcoming book Marvel Comics: The Untold Story. In it Kramer debuts this never-before-seen concept art and explained their vision for the movie:
"We're going to make an epic picture on the scope of 2001: A Space Odyssey with the kind of soundtrack that that film had, only using contemporary rock and roll," Kramer said at the time. "It's even conceivable that the Surfer might have a chant or a fanfare made up of one thousand electric guitar[s]. Doing the Silver Surfer has always been a dream of mine, and now it's going to be realized."
Oh yeah, and it would have starred his current girlfriend in the 80s, Olivia Newton-John. I would absolutely get high and watch that.
