Karla Schramm on AllMovie

Apparently something of a child prodigy, the screen's second "Jane," Karla Schramm, had traveled the world as a child pianist and even enjoyed some renown as a composer. After playing a bit part in D.W. Griffith's Broken Blossoms (1919), Schramm replaced one Evelyn Farriss in the role of Jane opposite former New York fireman Gene Pollar's Lord of the Jungle in The Revenge of Tarzan (1920). Apparently, Miss Farriss got so frightened of the prospect of appearing opposite sundry wildlife fauna that she declined the opportunity and the less fearful Karla became a last-minute replacement. Despite the fact that the redoubtable Mr. Pollar didn't exactly live up to his billing and that the seven-reel Numa Pictures release proved a rather embarrassing display of ineptness, Schramm survived unscathed and was retained as Jane in the serial The Son of Tarzan (1920). This time, however, Jane and Tarzan (elderly P. Dempsey Tabler) were merely supporting characters, as the main focus was on the ill-fated Kamuela C. Searle, who played the title's "son." This 15-chapter serial, alas, proved Miss Schramm's final screen appearance.
