In 1931, MGM, adapting author Edgar Rice Burroughs's popular Tarzan adventures for the screen, selected Brix to play the title character. But Brix broke his shoulder filming the 1931 football film Touchdown, so swimming champion Johnny Weissmuller replaced Brix and became a major star. After Ashton Dearholt convinced Burroughs to allow him to form Burroughs-Tarzan Enterprises, Inc., and make a Tarzan serial film, Dearholt cast Brix in the lead. Pressbook copy has it that Burroughs made the choice himself, but, in fact, in his biography, Brix confirmed that Burroughs never even saw him until after the contract was signed, and then only briefly. The film was begun on location in Guatemala, under rugged conditions (jungle diseases and cash shortages were frequent). Brix did his own Stunts, including a fall to rocky cliffs below. The Washington Post quoted Gabe Essoe's passage from his book Tarzan of the Movies: "Brix's portrayal was the only time between the silents and the 1960s that Tarzan was accurately depicted in films. He was mannered, cultured, soft-spoken, a well educated English lord who spoke several languages, and didn't grunt."
