CinemaBlend points us to a Star Trek Into Darkness press conference in Berlin, where director J.J. Abrams expressed support for the idea of veteran Star Wars composer John Williams returning to the conductor's stand for a little sequel project that Mr. Abrams will soon be directing. "For Star Wars," Abrams said, "it's very early days ... but I believe that ... John Williams will be doing that film, because apparently he was there long before I was." Check out the press conference video below. Abrams' comments about Williams occur at 8:14.
