Several modern sources credit this film as the first werewolf picture ever produced. It is sometimes referred to as Wolfblood and Wolfblood: A Tale of the Forest.
       Referring to the film as The Wolf Man, the 10 Nov 1923 Camera! announced the forthcoming feature from Ryan Bros. Productions, and printed the cast list which included Jack Cosgrave as “Maxwell Ford,” Tommy Ryan as “Bill Glennen,” and John McLaughlin as “Bruce Barton.” At that time, Ray Hanford’s character was listed as “Dr. Eugene Mindel,” instead of “Dr. Eugene Horton.” According to the 24 Nov 1923 Camera! John Gilbert’s latest Fox Film Corp. production was also using the title The Wolf Man (1924, see entry).
       On 17 Nov 1923, production charts in Camera! reported that filming was in its third week, and indicated that Ryan Bros. Productions was sharing studio space at the Famous Artists Studios located at 6046 Sunset Boulevard in Hollywood, CA. Subsequent charts through Dec 1923 listed weekly production updates, concluding with the ninth week of shooting in the 29 Dec 1923 issue.
       Noting the title change to Wold Blood, an advertisement in the 29 Dec 1929 Exhibitors Herald announced that principal photography was completed.
       Nearly a year later, the 10 Nov 1924 FD reported that the Lee-Bradford Corporation had signed on to distribute the independent picture, which would be sold through the states’ rights market.
       The 24 Jan 1925 Exhibitors Trade Review stated that the film was “now ready for release,” and referred to it with the alternate spelling, Wolfblood. However, a 2 May 1925 Motion Picture News release chart indicated that theatrical release would not take place until Oct 1925. Wolf Blood was not reviewed by Motion Picture News until 28 Nov 1925. In praise of the the film, the publication noted “plenty of thrills, brisk action, [and] well photographed.”
       The picture was fully restored by The Film Foundation, an organization founded in 1990 by director Martin Scorsese.
