The rumor stems from a Taiwanese Blu-ray 3D release of Dr. No, and the fact that Moviefone has created an entry for an IMAX 3D re-issue. Nothing has been confirmed by Sony Pictures or MGM Studios, both of which distribute the James Bond movies. Since Skyfall was the highest-grossing 007 movie of all time, the dashing character's popularity has been skyrocketing, so it wouldn't be terribly surprising to see the studios trying to cash in on Bond's resurgence.
Fox Home Entertainment handles the domestic Blu-ray and DVD releases for the franchise. Last summer, the studio made the surprise announcement that they converted the 2D sci-fi movie I, Robot for a Blu-ray 3D release. If a Dr. No 3D theatrical release is in fact in the works, then we can most certainly expect a domestic version of the first 007 movie on Blu-ray 3D.
Dr. No was released May 8th, 1963 and stars Sean Connery, Ursula Andress, Joseph Wiseman, Jack Lord, Bernard Lee, Anthony Dawson, Zena Marshall, John Kitzmiller. The film is directed by Terence Young.
