While walking the red carpet, Heigl, who got her big break on Grey’s Anatomy several years ago, spoke about her TV comeback on political drama State of Affairs. According to Heigl, who has gotten a reputation for being a bit difficult to work with, her return to TV sees her more involved in the process than ever.

“I don’t think I knew how much I would enjoy diving so deeply into it. I love getting to have a voice, and getting to participate in creative decisions,” Heigl told The Wrap, adding, “Getting to have something to say about my character’s story line, about her as a person, her tragic flaws, her brilliant moments, the music and the casting… I’ve just really had an incredible time getting my feet wet like this.”

In addition to the new TV show, Heigl also has a feature film that will soon be heading to theaters – Home Sweet Hell – a comedy thriller that also stars Patrick Wilson, Jordana Brewster and Grey’s Anatomy’s Kevin McKidd.

“It’s a big Sony movie, and it was just a huge opportunity for me to get involved,” Kelley, who composed the score for the movie, told Country Weekly. “It’s like a female version of American Psycho. It’s awesome and going to be amazing!”
