If you love movies, or even like them, take a moment to remember Arthur Widmer, who passed away today (aged 92!). This is the guy who created the "blue screen" effect, which was a huge leap in special effects. Now people could appear in virtually any surroundings, while filming safely and comfortably in the studio. It let filmmakers do things that were really impossible to do before, and let their imaginations soar. So thank you, Mr. Widmer, your contribution to FX brought tonnes of enjoyment to so many!
