Alfred L. Werker was a film director whose work in movies spanned from 1917 through 1957. After a number of film production jobs and assistant directing, Werker co-directed his first film, Ridin' the Wind in 1925 alongside director Del Andrews. He was brought in by Fox Film Corporation executives to re-shoot and re-edit Erich von Stroheim's film Hello, Sister! (1933), co-starring Boots Mallory and ZaSu Pitts.

Hello, Sister! is a 1933 American pre-Code drama-romance film produced by Fox Film Corporation. It was directed by Erich von Stroheim, Raoul Walsh, Alfred L. Werker, and Edwin Burke, although none of those directors are credited. The film is a re-edited version of von Stroheim's now-lost film Walking Down Broadway.
