HETEROSEXUAL males of a certain leaning who might look forward to a film where Heather Graham becomes a lesbian will be sorely disappointed here.

Gray Matters joins Graham and Thomas Cavanagh (JD's brother from Scrubs) at the hip as brother-and-sister Gray and Sam who get on probably a little too well for siblings.

Gray finds Sam a girl at the park, which he quickly proposes to and weds, but not before the girls have a drunken tongue wrestle.

So, to recap, brother and sister fall for the same girl. A rather grotty premise, really, and one that fails to excite at every turn.

Graham's atrocious acting doesn't help much, either.
