A+E’s History drama Project Blue Book grossed 3.1m total viewers for its premiere last night, making it the most-watched scripted series premiere in six years.

The company says the premiere telecast alone became the network’s most-watched scripted series premiere since the March 2013 premiere of hit series Vikings.

In addition, A+E says the premiere was the top scripted series on cable of the 2018/19 TV season across all key demos and total viewers.

The episode is said to have grossed 1m adults aged 25-54 and 771,000 adults aged 18-49 over the course of the night.

The ten-episode drama executive produced by Academy Award winner Robert Zemeckis (Forrest Gump), is based on the true, top-secret investigations into Unidentifed Flying Objects (UFOs) conducted by the United States Air Force in to 1950s and 60s.

Project Blue Book is an A+E Studios production in association with Compari Entertainment, a division of ImageMovers.

Zemeckis, Jack Rapke (Cast Away, Flight) and Jackie Levine (Allied, The Walk) are executive producers for Compari Entertainment. David O’Leary serves as creator, co-executive producer and writer, with Sean Jablonski (Suits) serving as showrunner, executive producer and writer.

Barry Jossen serves as executive producer along with Arturo Interian for History.

The title joins History’s original scripted roster, which includes anchor hit series Vikings and the Knights Templar drama series Knightfall, which will premiere its second season this spring with Mark Hamill (Star Wars) joining the cast.
