The casting of Captain America, Marvel’s latest action-adventure blockbuster, may be the most chaotic, rumor-filled and err, “open” campaign in recent Hollywood memory. First, a “short” list was leaked a couple weeks ago, revealing Chance Crawford, Scott Porter, Michael Cassidy and three other steel-jawed blond dudes as contenders. John Krasinski from The Office also joined the frenzy — an unlikely if amiable choice (go John!). Now, rumor has it Dane Cook and — brace yourself -= the Jonas Brothers have auditioned. Cook broke the news on his Twitter feed, tweeting:

The JoBros report, on the other hand, comes courtesy of the bastion of journalistic integrity that is Hollywire: “It was said Kevin Jonas had the better audition and was more natural.” Hollywire also suggests Miley Cyrus as a possible future Wonder Woman. Of course, the fight for Captain America can only go on for so long. Cassidy and Porter have already let us know they’re out of the running via Twitter and Facebook. The flick is due in theaters July 2011.
