With new pics out and a footage screening at Comic-Con's Hall H, Thor and its star Chris Hemsworth are causing serious buzz.

E!'s own Ben Lyons caught up with Chris last weekend at the pop-culture convention and talked to the upcoming god of thunder about some friendly competition with brother Liam Hemsworth, aka Miley Cyrus' BF, over the role:

"We were both rally for each other," Chris told Ben. "We're competitive but supportive. We don't talk much since," Chris joked, "but he should return my calls."
