His traditional German first name Karl is difficult for many non-Germans to pronounce, so his oriental sidekick Hadschi Halef Omar prefers to call him "Kara".
Kara Ben Nemsi, a German hero-adventurer of the 1880s, is actually a kind of superman (as was Doc Savage later), not only speaking dozens of foreign tongues fluently but also being able to knock out everybody with just one blow to the temple.
He rides his famous black stallion Rih as well as Frank Hopkins could, and is such an excellent marksman he could work in Wild West shows.
Hadschi Halef Omar (played by Heinz Schubert, best known from the German version of the British television series Till Death Us Do Part, is the hero's scout and his teacher when it comes to oriental conventions.
The director engaged many popular guest stars, including Ferdy Mayne, Heinz Baumann, Dieter Hallervorden and Willy Semmelrogge.
