The serial was shot under the working title Tarzan the Invincible and was released as Tarzan the Fearless. The " Tarzan yell" was the James Pierce version, taken from the radio series. A score was later taken from old westerns and "minutes passed" with silent (no sound effects, music or dialogue) stock footage of distant animals. The "serial was extremely crude" and "almost devoid of music" as well as suffering from poor sound. However, despite their initial problems, Lesser and Burroughs became friends and later worked out a five-picture deal (at one per year). Burroughs had assured MGM that their contract was exclusive, so the rival production was an embarrassment. Lesser never made another serial with his options, moving to feature films instead. Tarzan the Fearless was the first of Sol Lesser's Tarzan productions. MGM paid Lesser to delay production until their film was released. Lesser announced his own Tarzan production a few weeks into the filming of MGM's Tarzan the Ape Man. However, due to the wording of the contract the courts found in Lesser's favour and held that it was still valid. That producer went bankrupt and the contract was thought to have lapsed. Producer Sol Lesser had acquired the rights to five Tarzan films that Edgar Rice Burroughs had optioned to an independent producer in 1928.
