Trivia

A prologue summarizing the first three Tarzan films was added to the beginning of the serial.

The producer hired Norman Tuckey' (music) and Osborne Tedman (lyrics) to write the first Tarzan song, "Tarzan, My Jungle King," sheet music. "Written and composed especially for Son of Tarzan" (which was, ironically, a silent movie).

"Numa", the lion in this film, was the first lion--then called "Leo"--used when the MGM logo appears at the beginning of that studio's films.

Gordon Griffith plays Jack as a child ? Motion Picture News says "Jack, 'The Son of Tarzan,' age 15 years ... Gordon Griffith", and 'Korak, Jack five years later ... Kamuela C. Searle.'"

Musical Suggestions for "The Son of Tarzan" S.M.Berg has written musical scores for an each episode of "The Son of Tarzan" and also makes an important announcement in connection with the musical numbers suggested. Mr. Berg says: "In order to meet the requirements of exhibitors throughout the country who are declining to pay the tax demanded by the American Society, the musical suggestions are confined to such music as can be publicly performed free of all tax, as neither the publishers nor composers of the music suggested are members of the American Society of Authors, Composers and Publishers. "The timing of the picture is based on a speed of fourteen minutes to a thousand feet. End of reels is not given, because progressive operators either join reels together or diffuse so quickly that an audience or musician is not aware of the changes. The time indications will help the leader to anticipate the various cues, which may consist of the printed sub-title (marked T) or a described action (marked D). For instance: 28 3/4 T, 'Come to my home,' is a sub-title, and is printed reading matter on the screen. But 26 D, ' When ape seizes Tarzan,' is a description of action." In order to musically interpret ' The Son of Tarzan,' four contrasting themes will be found necessary. TARZAN THEME is an original composition, entitled "Tarzan, My Jungle King," by Stuckey and Tedman, and will be found particularly adapted to associate with the leading heroic characters of the story. The character of the composition is an Allegretto 4/4. JUNGLE THEME is 'A Cannibal Carnival,' by Sol P. Levy, and is suggested to be played at scenes of the jungle which is the lure to Tarzan's son, Jack. The tempo is a Characteristic Moderato Barbarique. Judicious effects of animal noises should be used in conjunction with this theme. PAULVITCH THEME, selected for the villain, Paulvitch, is " Sinister Theme," by Vely, the tempo being a Characteristic Ominous Dramatic. SHEIK THEME is ' Heavy Mysterioso,' by Sol P. Levy, the tempo being a Dramatic Characteristic. Although not strictly an Oriental number, the Sheik is the second villain in the serial, and requires a dramatic characteristic to interpret his nefarious schemes.
