Referring to the picture by its early working title, The Untamed, the 27 May 1925 Var announced the picture as Rudolph Valentino’s first starring vehicle for United Artists Corp. Principal photography was set to begin on 8 Jun 1925 at the United Studios in Hollywood, CA. Actors Wallace Beery and Tully Marshall were listed as supporting cast members, however, credits in contemporary reviews do not confirm that either appeared in the film.
       The 18 Jul 1925 Moving Picture World stated that production was underway, and reported a title change to The Black Eagle. Two days later, the 20 Jul 1925 Var announced a third retitling to The Lone Eagle, and noted a $400,000 budget. United Artists had scheduled a 27 Sep 1925 release date, which required the picture to be completed and edited within six weeks. However, the eventual release was delayed until 8 Nov 1925. The title change was deemed necessary due to another United Artist feature with the same name, according to the 1 Aug 1925 Exhibitors Trade Review.
       The 12 Aug 1925 Var and the 29 Aug 1925 Motion Picture News listed actress Barbara Tennant amongst the cast.
       On 26 Aug 1925, Var reported that production was nearing completion, and the 13 Sep 1925 FD announced that the picture was currently being edited and titled.
       According to the 16 Sep 1925 Var, which referred to the picture by its release title, The Eagle, Rudolph Valentino was trampled and kicked in the face by a runaway horse during production, and sustained injuries to his ankle and wrist. However, no delays resulted, and filming resumed the next day. The Oct 1925 Picture-Play stated that the comedy gave Valentino the rare “opportunity to be unexpectedly humorous,” and he reportedly employed three unnamed writers to get “just the right story.” Hans Kraly, longtime scenarist for Ernst Lubitsch, received credit for writing the final draft.
       According to the Library of Congress American Silent Feature Film Survival Database, this film is extant. The Eagle was screened at the 2006 Kansas Silent Film Festival in Topeka, KS, on 25 February 2006.
