Comic-Con has been an amazing experience. It's overwhelming, I have to admit, because of the lines and the crowds.

I would definitely line up for 'The Lord of the Rings.' I'm a huge 'Lord of the Rings' geek.

I'm helping launch the new Milky Way Chocolate Ice Cream Bar. I play an astrophysicist on television, and the name of the bar is Milky Way, so put two and two together, and here I am.

We live in a bubble sometimes, and you can get out of touch with your fans. You go to the studio, you come home. But coming to Comic-Con is a real opportunity to connect with the people that made your show happen and are responsible for its continued success. It's really humbling.

I'm obsessed with 'Game of Thrones.' I love comedies - I really like '30 Rock' and 'Modern Family.'

These characters, they have to evolve. They're getting older on the show, these are things that happen in everyone's life. People do get married... this is just a natural evolution. I wonder if we'll have 'Big Bang' babies in the season finale?
