The set up may be swiped from Hitchcock but the setting is drastically different.
One interesting thing to note about the similarity between this and Strangers on a Train is that they don't just share a similar plot but that, most will agree, Hitchcock's film also featured the portrayal of homosexual desire.
Things have changed quite a bit in Hollywood since then – although not really enough, I would argue – so the sexuality of the characters in Breaking the Girls can at least be front and centre and not just hinted at.
I do get the feeling from this trailer that lesbianism is being considered something of a selling point, though, at least in the eyes of those marketing the film. But I have enough faith in Jamie Babbit, who also directed But I'm a Cheerleader and worked on shows like The United States of Tara, to assume that the film isn't going to be just about attempts to titillate the audience.
Breaking the Girls is out in limited cities in America on the 26th of July.
