Aidan Gillen is not mourning the loss of Petyr's "Littlefinger" Baelish.
The 50-year-old Irish actor, who starred as the self-made lord and schemer in HBO's "Game of Thrones" from 2011 until 2017, told Fox News he's not sorry to see his character go.
Fans of the fantasy drama still remember when Baelish met his end of the season 7 finale. Sansa Stark (Sophie Turner), her sister Arya (Maisie Williams) is taken out in the process of slitting his throat.
"It was brilliant to be part of 'Game of I do not know what, what seven seasons, "Gillen said. "But it's so nice to be done with that, walk away and find a new suit to put on. For me anyway, it's always happening right now. That's the exciting thing. And that's what I'm doing. And everything else takes place in the background. "
And Gillen has already moved on from the master manipulator. In fact, Gilles is currently starring in a new mystery series on the History Channel titled "Project Blue Book." The show, which is based on a true story, explores US. Air Force-sponsored investigations into UFO-related phenomenon from 1947-70. Gillen plays Allen Hynek, at astrophysicist who serves as a consultant on the UFOs
Hynek is credited with coining the phrase "close encounters of the third child" to describe humans meeting aliens from outer space. He later served as technical adviser to the 1977 Steven Spielberg.
Gill said he did not hesitate to take on the role.
"I've been a child of fascinated with this subject since an early age," he explained. Spielberg to make one of my favorite films, the first film I ever went to see my own in the cinema, 'Close Encounters of a Third Kind,' what a no-brainer. "
The real-life Hynek passed away in 1986 at age 75 of a malignant brain tumor. However, Gillen shared his opinions as support and served as advisers.
"For my own part, I guess there is a lot of material there," Gillen said. "Hynek had written books and a lot of onscreen stuff that was available to watch. Of course, I read all that I could find and glean from that. But we were lucky enough to have some access to the Hynek family, in particular, Paul and Joel, two of his sons, who would share more personal insights and little things like family photographs, which were not little to me .
"It was really great to have them involved. My big thing was I just wanted to know what it means to be outside the public eye, off camera – as a family man. Because I reckoned that in my life and his passions were rooted in the love of family and earthly things. "
Gillen added that each episode of "Project Blue Book" on an actual case. David O'Leary intended to make use of as many as he could – or at least the "juiciest."
"To work in a genre that is associated with fantasy, or make-believe, or the imagination, and which is unique, said Gillen. "Sci-fact as opposed to science fiction."
And Gillen was not the only one meticulously studied for his new role. Gilles co-star Michael Malarkey of "The Vampire Diaries" Michael Quinn, who is based on Edward J. Ruppelt, the Air Force officer involved with Project Blue Book.
"… I have somebody I know who's in the Air Force who says the 35-year-old British-American Fox News.  Wright-Patterson Air Force base, which is where the Blue Book headquarters was written.
"I went into Wright-Patterson to do a lot of my preliminary research. Gilles is aware he may never escape his "Game of Thrones" past.
But these days, he said, "I'm taking on characters all the time," he said. "It always feels good, whatever the latest one is, that's where it's happening, you know? … I know the 'Game of Thrones' thing is still very current for me and I talk to people about it every day, but I'm Hynek now. "
