"I realize that delving into the world of assassination research and a belief in a conspiracy will lead some to brand me as an extremist or a nut, but the facts I have uncovered are so compelling that I must make the case that Lyndon Baines Johnson had John Fitzgerald Kennedy murdered in Dallas to become president himself and to avert the precipitous political and legal fall that was about to beset him," Stone wrote in his 2013 book, written with Mike Colapietro, "The Man Who Killed Kennedy: The Case Against LBJ."
(The book, which accuses Johnson of complicity in at least six other murders, also quotes Richard Nixon - Stone's former boss - as saying "Lyndon and I both wanted to be President, the difference was I wouldn't kill for it.")
Sean Cunningham, a history professor at Texas Tech, said no evidence supported the theory.
"Johnson makes for a good story and is an easy way to explain things," he told the Daily Beast.
