The blue screen method was developed in the 1930s at [[RKO Radio Pictures]]. At RKO, [[Linwood Dunn]] used an early version of the [[Matte (filmmaking)|travelling matte]] to create "wipes" – where there were transitions like a windshield wiper in films such as ''[[Flying Down to Rio]]'' (1933). Credited to [[Lawrence W. Butler|Larry Butler]], a scene featuring a genie escaping from a bottle was the first use of a proper bluescreen process to create a traveling matte for ''[[The Thief of Bagdad (1940 film)|The Thief of Bagdad]]'' (1940), which won the [[Academy Award for Best Visual Effects|Academy Award for Best Special Effects]] that year. In 1950, [[Warner Brothers]] employee and ex-[[Kodak]] researcher [[Arthur Widmer]] began working on an [[ultraviolet]] travelling matte process. He also began developing bluescreen techniques: one of the first films to use them was the [[The Old Man and the Sea (1958 film)|1958 adaptation]] of the [[Ernest Hemingway]] novella, ''[[The Old Man and the Sea]]'', starring [[Spencer Tracy]].<ref name="cri">{{cite web|url=http://en.chinabroadcast.cn/2246/2005-2-14/90@206385.htm|title=Illusions Take Home First Oscars|date=14 February 2005|publisher=[[China Radio International|CRI English]]|access-date=21 January 2009|archive-url=https://web.archive.org/web/20050315004609/http://en.chinabroadcast.cn/2246/2005-2-14/90%40206385.htm|archive-date=15 March 2005|url-status=dead|df=dmy-all}}</ref> |
