This is the only chapter filmed for a proposed television serial. It stars a very young Steve Reeves (who would gain fame in the sixties playing Hercules in a series of international hit movies produced in Italy) as the Tarzan-like Kimbar. This pilot was made in 1949
It’s no surprise this didn’t go any farther. The dialog is substandard, and the acting worse. But Reeves makes an impression. And it’s an interesting curio. Neither Wikipedia nor imdb makes any mention of this production in Reeves’ credits. But if their other credits are correct this would be his first onscreen appearance.
