New "Passing on the Smile" Fan-Film Teaser Trailer - Harley Quinn's Origin

I received an email this morning from a guy who is working on a new fan-made film called "Passing on the Smile". Basically, the movie is all about the creation of Harley Quinn. She is an employee of Arkham Asylum in Gotham City & we all know that she turns into a villain ( and Joker's girlfriend ) ...but, how does it happen? I think this film is going to try & explain that. This is the teaser trailer & you also get a small glimpse of the Joker.
