Project Blue Book will be back for a second season.
The news was announced by History during Television Critics Association winter press tour on Saturday.
The network has ordered a 10-episode second season of the freshman series. According to The Hollywood Reporter, Project Blue Book is the most-watched new cable series to date, averaging 3.4 million viewers per episode after three days of delayed viewing.
The series is based on real-life investigations into UFOs conducted by the United States Air Force in the 1950s and 60s and stars Aidan Gillen (Game of Thrones) and Michael Malarkey (The Vampire Diaries).
Project Blue Book hails from creator David O’Leary. He also serves as executive producer, and writer, alongside Sean Jablonski who serves as showrunner, executive producer, and writer. Jack Rapke and Jackie Levine also exec produce.
“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,” Eli Lehrer, executive vp and head of programming at History, said Sunday in a statement. “[Robert] Zemeckis, A+E Studios and our extraordinary creative team have shaped a compelling narrative that is the perfect blend of historical authenticity and entertainment that inspires curiosity in our viewers to learn more. We’ve touched on a very relevant topic and look forward to a second season.”
