If you're in any way interested in independent horror/thriller cinema then you will have heard of the Twisted Twins (Jen & Sylvia Soska). Their work in short cinema has been prolific and multi-award winning and in 2009 they proved the saying "Go big or go home" true with the release of their feature length horror Dead Hooker in a Trunk which you can read the review for [here]. Three years and many many awards and commendations from critics and film makers alike later (Eli Roth being one of the Sisters most outspoken fans) and their new film American Mary is about to prove that the Canadian duo not only have longevity but also the recognition that they so deserve.
Empire Online are now featuring the trailer for American Mary and can be accessed [here]. Similarly there's a little peak at Mary and what's in the girls' Trunk directly below.
