He went to the US in 1929, where his British film experience gave him the background to find his way to the Broadway stage, where he appeared in various productions until coming to Hollywood in 1935.

His first film role was in Universal's Tailspin Tommy in The Great Air Mystery (1935) serial.

Worth left films after playing a gambler in The Adventures of Mark Twain (1944) and may have returned to the stage, although Social Security records have him in California until 1951.

In 1965 he retired to Albuquerque, New Mexico, where he lived with an older sister, Beatrice Gregg, a former actress.

Private cremation services took place at Fairview Park Crematory in Albuquerque.
