Roy Pomeroy (April 20, 1892 – September 3, 1947) was an American special effects artist and film director.
[1] Pomeroy's career began during the silent era, when he worked as a special effects engineer for Famous Players–Lasky and its successor studio Paramount Pictures.
Pomeroy was head of research at Paramount, and experimented on an ultimately unsuccessful device to add sound to the studio's large-format Magnascope process.
"[3] In 1928, Paramount decided it was ready to release an "all-talkie", a film with synchronized dialogue throughout rather than in select scenes.
However, the sound techniques were praised for their relative sophistication (the critic Mordaunt Hall noted that the audience "even heard a pen scratching its way over the paper as Evelyn Brent wrote a message"), anticipating many elements commonplace today; in particular, a scene in which one character is crying shows not the character crying but a reaction shot of her lover, placing the attention on his emotional reaction rather than insistently displaying the source of the sound.
