Title: The Adventures of Tarzan
Content:  The success of the serial The Son of Tarzan inspired Great Western Producing Company to approach Tarzan's creator Edgar Rice Burroughs about making another Tarzan serial. However, the rights for another Tarzan film were still retained by the Weiss brothers' Numa Pictures Corporation, the makers of the feature film The Revenge of Tarzan. When Numa discovered that Great Western had Elmo Lincoln, the first screen Tarzan, signed to play the lead, they agreed to a deal in which Great Western would produce the film while Numa would handle distribution. The story was based partially on two of the Tarzan novels, The Return of Tarzan and Tarzan and the Jewels of Opar, with the addition of some new material. The desert scenes were filmed in Arizona.

Title: Tarzan the Fearless
Content:  Producer Sol Lesser had acquired the rights to five Tarzan films that Edgar Rice Burroughs had optioned to an independent producer in 1928. That producer went bankrupt and the contract was thought to have lapsed. However, due to the wording of the contract the courts found in Lesser's favour and held that it was still valid. Lesser announced his own Tarzan production a few weeks into the filming of MGM's Tarzan the Ape Man. MGM paid Lesser to delay production until their film was released. Tarzan the Fearless was the first of Sol Lesser's Tarzan productions. Lesser never made another serial with his options, moving to feature films instead. 
Title: Tarzan's Greatest Adventure
Content:  films. The films would be shot on location and the first one would be called Tarzan's World Adventure. They were still looking for an actor to replace Scott. In October the producers announced Theodore B. Sillis had signed to direct. In November Hedda Hopper reported that Weintraub, unable to find a new Tarzan, has signed a seven year deal with Scott to play the role. The producer decided to make a different style of film. Tarzan's Greatest Adventure would present a grittier, more realistic Tarzan. A loner who could be as savage as his opponents, but could also speak eloquently and politely to allies. Tarzan would also be made vulnerable and not as invincible 
Title: Tarzan and the Trappers
Content:  Tarzan and the Trappers is a 1958 action adventure film featuring Edgar Rice Burroughs' famous jungle hero Tarzan and starring Gordon Scott, Eve Brent, Rickie Sorensen and Lesley Bradley. It was filmed as three pilot episodes for a television series which were edited into a feature film when the project was abandoned, and so was released in black and white rather than color, like other contemporary Tarzan films. The film did finally appear on television, but only in 1966. It was shot in Chatsworth, California.
Title: The Revenge of Tarzan
Content:  The Revenge of Tarzan (1920) is a silent adventure film, originally advertised as The Return of Tarzan, and the third Tarzan film produced. The film was produced by the Great Western Film Producing Company, a subsidiary of the Numa Pictures Corporation. The film was sold to Goldwyn Pictures for distribution. The film was written by Robert Saxmar, based on the 1915 novel The Return of Tarzan by Edgar Rice Burroughs, and directed by Harry Revier and George M. Merrick. It was released on May 30, 1920.
Title: Tarzan's Greatest Adventure
Content:  Tarzan's Greatest Adventure is a 1959 Eastmancolor adventure film directed by John Guillermin, produced by Sy Weintraub and Harvey Hayutin, and written by Les Crutchfield, based on the character created by Edgar Rice Burroughs. With a strong supporting cast that included Anthony Quayle and Sean Connery, and a focus on action and suspense, the film won critical praise as a Tarzan film that appealed to adults as well as children. The film features a literate Tarzan portrayed by Gordon Scott. The character of Jane, Tarzan's wife, does not appear and is not mentioned. At one point, Tarzan briefly romances a female character, suggesting that he is a loner, not a family man. Cheeta, Tarzan's chimp companion in many films, appears only a few times near the start of the film, and the kind of comic relief that Cheeta represents is generally absent from the film.
Title: Sy Weintraub
Content:  After World War II service in the US Army, he formed Flamingo Films with David L. Wolper, who acquired the television rights to Eagle-Lion Films in 1951. Starting in 1958, Weintraub took over the Tarzan franchise from Sol Lesser and began producing Tarzan films made on actual locations (most previous Tarzan films had been shot on studio sets, with stock jungle footage edited in). He decided to drop the character of Jane and portray Tarzan as a well-spoken lone adventurer, though the title character is allies with Jai and the chimpanzee Cheeta. Weintraub started with Tarzan's Greatest Adventure (1959) and its follow-up,

In 1965 Weintraub filmed three Tarzan films back to back with former Los Angeles Rams football star Mike Henry: Tarzan and the Valley of Gold (Mexico), Tarzan and the Great River and Tarzan and the Jungle Boy both filmed in Brazil.
