Tyrannosaur, with Olivia Colman and Paddy Considine.
Dark as F. Colman has, to me, been that great actor in the background, that's finally getting her just rewards. She's phenomenal, multi-faceted, sad, sympathetic. Considine, holy crap. The opening of the film had me believing there was absolutely no way I would every give a rat's tiny ass about this horrible man. And then I did.
Amazing performances. Highly recommended.
