O Fantasma do Louvre

A ghost has been seen during the night in the Louvre Museum (Paris), and a guard is found dying near the statue of Belphégor, a god of Moabites and Ammonites. A young reporter, Jacques Bellegarde, begin to investigate but soon he’s being threatened by some letters sent by … Belphégor
It’s a silent mini-serie in 4 parts, after a popular book of Arthur Bernède, in the style of the 1st Fantômas (in fact, René Navarre was Fantômas in the Louis Feuillade’s movie)
Nearly 40 years later, a remake of this serie was made with Juliette Greco and met a great success in France, and is much better known that this one.
