I love this. I have to give Marvel some major props for going for unexpected, but friggin amazing actors for there movies. I didn't think they could outdo Robert Redford for WTF (in a good way) casting, but now they have.
Another good choice for exposure to Glenn Close is Damages. Great show. It also stars X-Men: First Class's Moira McTaggart, Rose Byrne, and over the seasons it's also features Ted Danson, Nikita's Noah Bean, OUAT's Anastasia Griffith, William Hurt, Marcia Gay Harden, Justified's Timothy Olyphant, John Goodman, Martin Short, John Goodman, Spartacus's John Hannah, Jenna Elfman, and a lot of other great actors.
