According to ComicBook.com on Sept. 2, rumors have been flying around most of the day involving information about the "Star Trek Into Darkness" villain, Benedict Cumberbatch, who may be appearing in J.J. Abrams' "Star Wars VII" film. Later on, some news sources have denied these rumors to even be a possibility, but there is some information that may bear some kind of significance.
But a particular news source is apparently of the thought that they aren't entirely certain it is a completed deal, but they also do not entirely believe the denials that they have been hearing. The wonderment of the situation stems from entertainment press officials not even making denials at this point and thus are not even sure themselves what to make of the scenario outside of any kind of official statement stemming from J.J. Abrams and his crew.
There is some significance to consider here that BadA** Digest, which is a publication that had been covering the film project, did hear that Cumberbatch will be appearing in all three "Star Wars" sequels and possibly a Sith Lord. He was also thought to be a major player in the "Star Wars" mythology.
The press source in questions had this to say in regards to Cumberbatch's dropping out of certain film projects:
“This part is why he dropped out of Guillermo del Toro’s Crimson Peak. But it’s not a done deal, and it may not yet come together. There are some other commitments Cumberbatch will have to break to secure the part".
One could bring to the table that it's just simple logic that Cumberbatch would have to give up certain film projects in order to make time for J.J. Abram's film.
