If you've been to the movies this century, then you're already familiar with blockbuster film composer Henry Jackman's music. In flicks ranging from X-Men: First Class to Big Hero 6, this Hans Zimmer disciple is a pro when it comes to marshalling soaring strings, boisterous horns, and thumping timpani in the service of advancing Tinsel Town's biggest stories. Conjuring mystery, suspense, intrigue, and triumph, Jackman's compositions are a rallying cry for heroes such as G.I. Joe, Captain America, and even Puss In Boots.
