We’ve all seen the real dolls, the life-sized and eerily lifelike sex dolls which featured in the hit indie flick Lars and the Real Girl. But have you ever wondered where they came from? In this video, sex doll artist Matt McMullen opens up about his passion.

Matt is a slightly creepy but oddly fascinating fellow who takes his creations seriously, so much so that he’s admits giving them a test drive.

Needless to say, this isn’t the kind of video to watch when you’re at work or in the company of small children. Boobies and other bits abound, even if they are synthetic. But if you’re home alone, this is one interesting short film.
