Another parody to reach high class.

“Fakham Hall” almost reminds me of how “Airplane” was conceived. I’m told that the filmmakers were taking the spoofing genre seriously by remaking “Zero Hour” and adding funny stuff in the mix. “Fackham Hall” (which sounds a lot like “F*** Them All”) is a parody of “Downton Abbey” and a little bit of Agatha Christie mysteries with Hercule Poirot, and it has class.

I’m convinced this spoof likes to be taken a little more seriously by casting professional actors like Damian Lewis, Katherine Waterston, Thomasin McKenzie, Emma Laird, and Tom Felton. And I’m also convinced it wants to go for that “Naked Gun” and “Airplane” approach, when it goes for jokes in the foreground and background. When men go hunting, a deer falls from the sky, and when pop star names are snuck in, we don’t get second or third rate actors lampooning them.

Like last summer’s “Naked Gun” spiritual sequel with Liam Neeson, “Fackham Hall” is another piece of evidence that the spoof genre is making a comeback, and allows British humor to kick in. So domestically and internationally speaking, parodies can be parodies. Monty Python knew how to do it back then, and maybe writers Jimmy Carr and the Dawson Bros, and director Jim O’Hanlon can try to live up to their style.

Fackham Hall is owned by the Davenports-led by Lewis and Waterston as Lord and Lady Davenport-and a wealthy marriage should save it from financial ruin. Threatening its chances is the pickpocket Eric Noone (Ben Radcliffe), who is fresh out of the orphanage that has been “Recycling Children Since 1808.” He gets a job at the mansion as a servant, and sparks a forbidden romance with the youngest Davenport Rose (McKenzie), who refuses to marry the wealthy Archibald (Felton). But her family wants her to, since her older sister loves another.

That’s when Inspector Watt (Tom Goodman-Hill) comes in. I don’t know what. No, “Watt” is his surname. He’s here to investigate a murder, which is pinned to Eric. He has to follow the formula that he doesn’t want the family to know he and Rose have been sneaking out to a local pub. You know how rich people would react to a rich girl and poor guy being in love.

We do get some obligatory poop jokes, but we also get some fancy tickles and a reminder of the good old days of spoofs. I knew “Fackham Hall” would know what it was trying to do, when I found out the casting choices. McKenzie has already proven her worth with movies like “Leave No Trace,” “The Power of the Dog,” “Last Night in Soho,” and “Eileen.” And in this comedy, she delights us with her sweet and sensitive nature, and how literal she can be at times. Like when she’s asked “How did you sleep?,” she responds with something like “With my eyes closed.” And I like how Lord Davenport gets shot and appears to be bleeding, but something bulletproof saves him. It always has to act sad, but it doesn’t give us the finger about it. And after seeing Dwayne Johnson flip off Zac Efron after saving his life from drowning (and he thought he was kissing a woman) in “Baywatch,” I like to tell that movie to “Fack” off.

I think the key to spoofs is that the comedy writers take the material seriously and the laughs flow naturally. It’s about how to target the movies and shows, how to satirize them, and how to balance honesty with goofiness. Maybe it wants to try to be taken seriously, but it also wants to have a good laugh. It’s R-rated, but it doesn’t curse to be funny. It’s all part of my honesty theory. Even “Downton Abbey” fans won’t be insulted by this lark.
