A documentary highlighting some of the oddest, strangest and more grotesque examples of human behavior. Included are a tour of the Grand Guignol theater in Paris, a man who sticks long needles through his body, reindeer being castrated, and footage of lesbians and strippers.
Unfortunately the movie Ecco is not yet available on Disney Plus.
