History has renewed its sci-fi-themed series Project Blue Book for a second season, the network announced during its Television Critics Association winter press tour presentation.

Project Blue Book, based true, top-secret investigations into Unidentified Flying Objects (UFOs) conducted by the United States Air Force in the 1950s and 1960s and stars Aidan Gillen (Game of Thrones) and Michael Malarkey (The Vampire Diaries), is averaging 3.4 million viewers in Live+3 delivery, according to network officials.

“We are believers in Project Blue Book and so is our audience who has sparked a conversation about the hundreds of unsolved cases and our nation’s military response to UFOs that have remained relatively secret until now,” said Eli Lehrer, Executive Vice President and Head of Programming for History in a statement. “We’ve touched on a very relevant topic and look forward to a second season.”

The network also set an March 25 premiere date for the sophomore campaign of its drama series Knightfall. Mark Hamill (Star Wars franchise) will join the cast of the show, which goes inside the medieval politics and warfare of the Knights Templar, the most powerful, wealthy and mysterious military order of the Middle Ages.

History Wednesday released a first look trailer for the second season of its drama series Knightfall, which will feature actor Mark Hamill.

Knightfall, which explores a dark time in history from the perspective of the Templar, casts Hamill in the role as Talus, a battle-hardened Knight Templar veteran of the Crusades. 

Talus survives captivity for 10 years in the Holy Land and is tasked with training the new initiates to the Order, according to History.

Knightfall is produced by A+E Studios in association with The Combine and Midnight Radio, with Aaron Helbing, Jeremy Renner, Josh Appelbaum, André Nemec, Jeff Pinkner, Scott Rosenberg, Don Handfield, Richard Rayner, Cyrus Voris, Ethan Reiff, Rick Jacobson, Arturo Interian and Barry Jossen serving as executive producers, according to the network.

German sci-fi fans in need of a stiff midichlorian fix will get that and then some come December, when satellite giant Sky Deutschland turns over its Sky Hits channel into Star Wars HD channel for two weeks, dedicated to airing all six movies in the canon.

The movies will be shown in their narrative order – starting with 1999’s Star Wars: Episode I: The Phantom Menace and ending with the 1983 Star Wars: Episode VI: Return of the Jedi. In addition to the films, the channel will air documentaries and featurettes about the iconic science fiction franchise. The launch comes about a year before The Walt Disney Co., which purchased Star Wars creator Lucasfilm in 2012, is slated to release the next film in the franchise – Star Wars: Episode VII, which will bring back actors from the original trilogy including Mark Hamill, Harrison Ford and Carrie Fisher.

“We are well aware that December 18th 2015 is much too long for fans to wait until the release of Star Wars: Episode VII. Many thanks to our outstanding partners Disney and Lucasfilm for the opportunity to exclusively offer Sky Star Wars HD,” said Sky Deutschland executive vice president of programming Gary Davey in a statement. “For someone who has been a Star Wars fan since the first film 37 years ago, this project is a dream come true. Anakin, Luke, Leia, Han – in December the entire Star Wars family is coming to one channel, around the clock. This is the sensation of the TV winter in Germany and Austria.”
