Thirty Days (1922) is a lost silent film.
Wallace Reid's final film. It was in theaters in January of 1923 as he struggled through his final weeks of morphine addiction/withdrawal. In what may be the low-water mark for "crassness" (even by Hollywood standards), the film was billed in newspaper ads with the catchy phrase, "Come see Wallace Reid's final picture!"--while he was still alive. No print of this film is known to exist and it (like most Wallace Reid films) is considered "lost".
