"Gillis and Woodruff share never before seen makeup designs they created for Ridley Scott's unproduced version of I AM LEGEND."
In the late '90s, Ridley Scott was attached to direct a film adaptation of Richard Matheson's novel I AM LEGEND. Eventually he left the project and it became the Francis Lawrence film, starring Will Smith. I think I would have enjoyed seeing Ridley Scott's take on the classic book. The practical effects created vampires in this test footage look way better than the CGI ones used in the later version.
