A collection of sci-fi movie memorabilia is heading to auction and includes one of the most iconic film aliens of all time. As part of the upcoming series, "There Are Such Things: 20th Century Horror, Science Fiction, and Fantasy on Screen," Sotheby's is offering an original, screen-used E.T. full body model seen in Steven Spielberg's E.T. the Extra-Terrestrial. Designed by the late, great special effects and makeup artist Carlo Rambaldi, the roughly 3-foot-tall piece of pop culture history was used in the famous "closet scene," and is one of just three manufactured during the making of the 1982 movie. While instantly recognizable today, E.T.'s overall look was completely absent from Melissa Mathison's screenplay. Creating the character from scratch came through a collaboration between Spielberg, storyboard artist Ed Verreaux, and Rambaldi.
