People wear masks with pictures of former NSA contractor Edward Snowden during the testimonial of Glenn Greenwald, the American journalist who first published the documents leaked by Snowden, before a Brazilian Congressional committee on NSA's surveillance programs, in Brasilia in this August 6, 2013 file photo. Sony Pictures Entertainment has acquired the film rights to journalist Greenwald's book about former Snowden, recruiting producers of the James Bond franchise to bring the story to screen, the studio said on Wednesday.
