It's finally here: Star Wars Episode 7, which will either make or break JJ Abrams's role in the Star Wars universe, will begin filming in less than 6 weeks. And even though we're literally a stone's throw away from seeing the filming begin, we're still not sure of the cast... and now, Castle star Nathan Fillion is in talks to star in the film!

According to Screen Crush, principal photography will begin on May 14, and it will take place in Morocco. Those who are fans of the original Star Wars will remember that the scenes on Tatooine were filmed in Tunisia, Yuma, and the Death Valley -- which all have the same terrain as Morocco -- so this is certainly leading to speculation that some of the scenes will take place on Tatooine... or maybe a whole new desert planet?

Naturally, of course, this is keeping with the same tradition of JJ Abrams's sworn-to-secrecy tactic of film-making... much to the disappointment of Star Wars fans, who expect more openness (not spoilers, though) when it comes to this momentous film.

Indeed, according to Metro U.K., the only person who is even remotely solid as a character is Adam Driver of "Girls," who will play a Darth Vader-like villain.

But, according to Movie Viral, Abrams is actually leaving digital clues as to whom he's cast in various roles, as well. Abrams was recently asked by a blogger about who was cast in the film, to which he replied, "The Dark Side is always where you least expect it. That's all I can say at this time."

The blogger noticed that Abrams was staring at a Star Wars logo with an IMDB link at the bottom of it.

The IMDB link is this: www.imdb.com/name/nm0277213 -- which is the page for Castle actor Nathan Fillion.

When contacted by Movie Viral if Fillion was, indeed, cast in the film, his reps simply said, "We can neither confirm nor deny Nathan Fillion's involvement in the new Star Wars film."
