The Thrill Chaser (1923)

Working as a motion-picture extra, Westerner Omar K. Jenkins (Hoot Gibson) impresses Sheik Ussan, a visiting Arab prince, with his pugilistic ability. Engaged to go to Arabia, he becomes involved in war between rival principalities and falls in love with Olala (Billie Dove), a princess who is promised. Omar is taken prisoner and readied for the chopping block when Sheik Ussan intervenes.
