Another addition is made to the ever-expanding (even this late in the game) Star Wars: Episode VII cast with JJ Abrams "good luck charm" Greg Grunberg. Also, we get some very enticing news on the significance for the new canon that upcoming Disney XD show Star Wars: Rebels will have.

As is usual for a JJ Abrams production, we can bring you a snippet of news, but not much more. Yes, Greg Grunberg will be in Star Wars: Episode VII as tweeted by the man himself, but the veil of secrecy covers everything else.

Don't expect the man who played the telepathic cop on Heroes to have a huge role in that galaxy far, far away or anyting, since his contribution to the Star Trek universe was playing the voice of lil' James T. Kirk's maternal uncle on the phone, yelling at the little guy for taking his classic car out for a joy ride.

Yes @smgulz it IS safe to assume I have a role in #StarWarsEpisodeVII - If I say more than that, JJ will have me killed. — Greg Grunberg (@greggrunberg) September 11, 2014

Meanwhile, expect Star Wars: Rebels to become a fertile breeding ground for concepts, vehicles and locations to be revisited once the live action movies come out. Said executive producer (and creative consultant on Episode VII) Simon Kinberg in an EW interview: “It’s a very integrated process, there’s real communication between all the filmmakers because we’re all part of a larger timeline. […] There is absolutely communication and integration between the different stories. We are very aware of what they’re doing in VII, and we also have to click into place with Episode IV. […] There are characters, vehicles, imagery that are introduced in the show before we’ve ever seen them in the movies, possibly including VII.”

Star Wars: Rebels premiers on Disney Channel October 3, then starts its run on Disney XD October 13.
