Sooner or later, based on her looks and her acting oeuvre, someone’s going to ask her to play Ann Coulter:
And it’s going to screw her up really bad– above and beyond having to go to a skeletal weight to play her, I mean.

I see exactly what you’re saying, but…Mercedes McNab is so lovely and charismatic, the mind involuntarily rebels at any thought of her features being transmogrified into that mannish, tightlipped, sour visage. It would be a feat of makeup and acting to rank with Charlize Theron playing Aileen Wuornos, but all you’d end up with is a film about a far less interesting character.
Besides, I’ve been thinking Jennifer Aniston would be a good choice to play Ann. I’m not disparaging Aniston’s looks! But at least she has the hard jawline and a way of narrowing her mouth tightly…and the acting chops to play a character who’s totally unsympathetic and dislikeable. When McNab was a regular on Angel, I kept rooting for her no matter what terrible things her character did. The thought of feeling empathy for THIS character, however, would make me want to slit my wrists.
Why don’t they just put a blonde wig on the velociraptor from Jurassic park?
Read that Coulter and George Carlin are both booked for Leno on Wednesday night. Not that there’s any guarantee that they would both be out at the same time, but I’d love to see Carlin unload on her. Cause I’m afraid the spineless version of Leno would just wither before her cold, clammy stare.
How about the anorexic Olsen twin (I can never remember which one achieved that ###### addict chic perfection).
