Wormholes and Swords is a blog dedicated to Science Fiction and Fantasy, with a bit of real world technical stuff thrown in from time to time. It is managed by T.D. Wilson, author of the Science Fiction book series, The Epherium Chronicles.
Disney released the first Teaser Trailer for Star Wars: Rogue One. The effects even in the trailer are really good. I am anxiously awaiting the next trailer that should have more Vader in it.
