Bryant Haliday is a ventriloquist named "Vorelli" who has a very bizarre act involving a wooden dummy that can apparently move on it's own.
The tension between Vorelli and the dummy named Hugo is amazing and very creepy and well done. William Sylvester is Mark English, an American reporter who suspects something is very wrong about the act. His girlfriend is Marianne Horn played by the beautiful Yvonne Romain.
This is a very well made film and it has a great twist ending that really knocked me out when I first saw it. Haliday does a good job as the evil ventriloquist. A must see film for horror fans. Beware Hugo!!
