There are plenty of other characters to get excited about in The Avengers besides the team of superheroes. We're probably most excited to see the bad-ass Cobie Smulders play S.H.I.E.L.D agent Maria Hill. This latest clip, which premiered on The Late Show with David Letterman, demonstrates the tense relationship between Hill and her boss, Nick Fury. I can't wait to see Hill throw down! The Avengers will hit theaters on May 4, 2012.
