May 7 (UPI) -- A&E Networks has opted not to renew the History channel shows Project Blue Book and Knightfall for third seasons.
Project Blue Book was based on the real-life experiences of Dr. J. Allen Hynek (Aidan Gillen), a college professor called upon by the U.S. Air Force to investigate unexplained mysteries, possibly involving aliens from other planets.
The series co-starred Michael Malarkey, Neal McDonough, Michael Harney, Laura Mennell and Ksenia Solo also star, with Keir O'Donnell and Jerod Haynes.
"Friends, very sad to report #ProjectBlueBook won't be renewed @HISTORY, who'll pursue mini-series only. BUT, know this: We are committed to finding it a new home! Now we need our 2.5mil+ weekly fans' help! #RenewBlueBook is now #SaveBlueBook! RT!" show creator David O'Leary tweeted.
Knightfall was a drama about the Knights Templar, set in the 14th century.
