Wesley Elsberry points out that Ben Stein has reported in an interview that he was approached for the "Expelled" project, described more or less as it finally came to be, back in 2006. Part of the pitch was that he was shown XVIVO's "Inner Life of the Cell" video.
Yet in April 2007 (a month after the "expelledthemovie.com" domain was registered), Mark Mathis obtained the cooperation of Genie Scott, P.Z. Myers, and other participants by pitching the nonexistent film "Crossroads," about the intersection of science and religion, from "Rampant Films," which had an innocuous website and an address at an empty apartment complex in Los Angeles.
Stein's interview provides further evidence that "Crossroads" was a dishonest subterfuge and that the "Expelled" crowd fully intended to use XVIVO's film in their movie and did not commission their copy until after William Dembski was sent a cease and desist notice in September 2007, delaying the film's release from February to April.
