I am not a great fan of Jean Yarbrough, I will put him as the same scale as Reginald Le Borg. Both had very close like careers, both made cheap horror films, both directed Joe Palooka's flicks. Not the best they let in audiences memories. But this one, thanks to Eduardo Ciannelli, is very exciting, though not as the same scale as a Jacques Tourneur's horror film such as CAT PEOPLE or LEOPARD MEN, or, more simple, the Val Lewton's productions. Yarbrough was not that good, but only a little horror films director whose most of this early work is uninteresting, unlike his second part of career stuff. This one is really worth for horror fans or gem diggers.
