The first-known feature-film credit for American screenwriter Raymond L. Schrock was 1915's Judy Forgot. Prior to his film work, Schrock was a playwright: One of his theatrical works was Leap to Flame, which he duly adapted to the screen. During the 1920s, he wrote comedies for performers like George Walsh and Johnny Hines, but also found time for the melodramatic comings and goings of Phantom of the Opera (1925). He spent the first few years of the talkie era at Universal, then resurfaced in 1939 at Warner Bros.' B-unit. From 1943 to 1949, Raymond L. Schrock kept busy at such bread-and-butter operations as Columbia, Monogram, and PRC.
