Could Pathe's Adam 11 have been an ancient precursor to the 1970s TV series Adam 12? Not at all. The title refers to a popular trained chimpanzee of the period; he was known formally as Adam the Eleventh, a jocular allusion to the Darwin Theory. The star chimp was undeniably talented, and his tricks were quite clever. Unfortunately, Adam 11 suffered from uninspired camerawork, completely nullifying the effectiveness of the simian's vaudeville act. Even worse, Adam the Eleventh performed before a dark blackdrop, which evidently was the same shade of brown as he, rendering the monkey utterly invisible at times.
