What’s really going up in there in the skies?

Ahead of this week’s San Diego Comic-Con, EW shared a sneak peek first look at History’s scripted UFO drama “Project Blue Book”, which depicts “Game of Thrones” alum Aidan Gillen discovering an alien that’s been obtained by the government.

Maleficent helmer Robert Stromberg, an Oscar and Emmy-winning production designer/special effects artist, directed the first two episodes of the10-episode series, which chronicles the true top secret U.S. Air Force-sponsored investigations into UFO-related phenomena in the 1950s and ’60s, known as “Project Blue Book.”

“’Project Blue Book’ follows Dr. J. Allen Hynek, a brilliant college professor recruited by the U.S. Air Force to spearhead this clandestine operation that researched thousands of cases, many of which were never solved. Each episode will draw from the actual files, blending UFO theories with authentic historical events from one of the most mysterious eras in United States history.”

Robert Zemeckis and his ImageMovers partner Jack Rapke (Cast Away, Flight) and the company’s Jackie Levine (Allied, The Walk) executive produce for Compari.
