In 1968 Mexico city was the host of the first Mexican international movie festival,and thats the reason why this film was made with international star Elizabeth Campbell(one of the hottest babes in Mexican films at that time)but that was the only good in this sordid film who have scenes bizarre who supposed makes you feel fear,but you cant stop laugh of scenes like a skeleton dance a go go with the male star when he have a nightmare or Elizabeth Campbell kiss another skeleton in the mouth meanwhile the skeleton hands grab her butt(go figure)curiously the Mexican critics of that time say this was a masterpiece,but thats not true for nothing.Don't waste your time and only see the parts of Elizabeth Campbell and the rest of the movie in fast forward,except if you cant sleep one night,put this in your DVD player and you fall sleep before 15 minutes when picture starts.
