Holy sweet Maria, the special effects in this movie blow away anything that is out these days. (The movie is from 1968. 40 years ago!)
Everything looks so REAL and the scenery, stage sets, wardrobe, everything, you name it. A lot of time was put into that shit.
The movie itself is pretty boring, and the ending is a complete mind-fuck that leaves you going,,,"uhhhhh,,,,wait, uhhh...." But SICK overall.
Netflix this shit if you are into visually appealing cinematography.
