In September 2005, Marvel chairman and CEO Avi Arad announced Black Panther as one of ten films being developed by the new Marvel Studios.[73] Marvel Studios received financing to produce the slate of ten films to be distributed by Paramount Pictures.[74] In June 2006, Snipes said he hoped to have a director for the project soon,[75] and Marvel Studios president Kevin Feige reiterated in February 2007 that Black Panther was in development.[76] By that July, Singleton had been approached to direct the film.[77] In March 2009, Marvel hired writers to help come up with creative ways to launch its lesser-known properties, including Black Panther;[78] Nate Moore, the head of the writers program, was overseeing the development of Black Panther specifically.[79] Snipes' involvement stalled at this time, as he was convicted of failing to file a tax return, serving his sentence from June 2010 to April 2013.[80] In January 2011, Marvel Studios hired documentary filmmaker Mark Bailey to write a script for Black Panther, to be produced by Feige.[81] By October 2013, the metal vibranium, which comes from Black Panther's home nation Wakanda, was introduced in the Marvel Cinematic Universe;[82] Marvel had considered showing Wakanda itself as early as Iron Man 2 (2010), but were waiting until they had "a full idea" of how to depict it.[10]
