Yesterday Creation Entertainment, the only company authorized to hold official Star Trek conventions, announced that they would be returning to Phoenix, Arizona in 2011. For those who may not know, the year 2011 marks the 45th anniversary of Star Trek. Creation is celebrating that milestone with additional cities added to their official Star Trek convention tour.

Creation Entertainment’s Official STAR TREK Convention LAS VEGAS: Celebrating the 45th Anniversary is heading towards our brand new venue, the Rio All Suites & Casino Hotel, and we’re rolling out the red carpet for fans throughout the galaxy to be with us for this history making event! It all happens August 11-14, 2011 and today we are VERY happy to announce that the incredible WILLIAM SHATNER will be headlining.

Well, well, well. Creation Entertainment has scored big for it’s monster Los Angeles salute to Firefly, Buffy/Angel and Dollhouse convention. The star of Dollhouse, Eliza Dushku, will be headlining the event. Joining her will be Nicholas Brendon (Xander from Buffy), Sean Maher (Simon from Firefly), and Morena Baccarin (Inara from Firefly).

This past weekend Creation Entertainment hosted the Official East Coast Star Trek Convention in Parisppany, New Jersey. On the guest list was George Takei, Jeri Ryan, Casey Biggs, Jeffrey Combs, Armin Shimerman, Max Grodenchik, Vaughn Armstrong, Nana Visitor, Ethan Phillips, and J.G. Hertzler (who was a last minute replacement for Jennifer Lien, who canceled). And for the record, J.G. Hertzler is the man. If you are a DS9 fan, you should absolutely try to attend a convention with him. You will not be disappointed. J.G. Hertzler is pretty much a Klingon in real life.

Two of science fiction’s biggest franchises are holding official conventions this weekend! Star Wars Celebration V, the official Star Wars convention hosted by ReedPOP, is happening in Florida. Meanwhile, Creation Entertainment is holding their Official East Coast Star Trek Convention in New Jersey. Both have some impressive guest lists and activities planned. We’ve already provided some coverage on them both, which we’ve re-linked below, along with some new information and what you can expect from our reporting team in terms of coverage during and after.
