Yesterday Benedict Cumberbatch was at the Conan O'Brien show promoting his new movie The Hobbit: The Desolation of Smaug. Of course tha Star Wars questions were not spared...
Conan asked, about the rumors that Benedict would like to be in Star Wars and that he is lobbying J.J. Abrams.
Cumberbatch humorusly dodged the subject saying that he was leaving casual messages on J.J.'s phone "as a light saber". But probably Abrams thought he was getting bad cell reception.
Later Benedict added that he went to a chat show and auditioned for Chewbacca and did his magic hence traumatizing Harrison Ford who was also at the audition.
You can see the video below though the sound quality is very low:
