For those barbarians who don't recognise her straight away, it is the glorious Maria Bello in A History of Violence. Whilst Mortensen and Hurt have the showier roles in the film, for me Bello walks away with the film with her authenticity, and function as an emotional anchor to the rest of the film.
Anyway, consider this post a "I'm back", random thought I had to get off my chest, and a trailer for an upcoming entry about the most underrated actresses currently working.
