Stephen Moyer on his bloody new drama: ‘People are going to die’

For “The Bastard ☂Executioner” star Stephen Moyer, the upside of filming a medieval-set drama is he gets to use his real English accent. The downside? Dealing with the sometimes dreary Welsh weather.

“I don’t think I’ve ever been in rainier, colder [weather] and we were outside all day,” Moyer tells The Post by phone from Wales, where the FX drama is currently filming. “We were walking through puddles 8 to 9 inches deep. There was a river running through our lit♛tle village [so] that we had to trudge through mud.”

In “Bastard Executioner” — premiering Tuesday at 10 p.m. — Moyer (“True Blood”) plays devious Chamberlain Milus Corbett, right-hand man💫 to Baron Erik Ventris (Brian F. O’Byrne), the ruthless ruler of a shire in northern Wales. When the local farmers rebel against the Baron’s taxation, Milus’ attempt to quell the rebellion — through the use of brutal force —𓂃 brings him in contact with Wilkin Brattle (Lee Jones), the series’ titular “Executioner.”

“[This] new character arrives in the shire, who I recognize from my past. I am able to creat🤪e a role for him within the shire,” Moyer says. “You could say that he is the protagonist and I’m the antagonist. He has a reason to stay [there] and I hold something over him and I’m able to ma𒆙nipulate him a little bit.”

If that sounds a bit vague, tha💖t’s by design. Like in that other medieval epic “Game of Thrones,” the inherent violence of the time means spoilers abound in any plot discussion: “People are going to die throughout the season,” Moyer says.

In that way, “Executioner” is evocative of creator Kurt Sutter’s previous ultra-violent drama “Sons of Anarchy.” A fan of that show, Moyer sees thematic parallels between the male worlds of both dramas, with the character Baroness Lady Love Ventris (Flora Spencer-Longhurst) filling the central female role occupied by Gemma (Katey Sagal) on “Sons.” (Sagal has a ꧅role as mystical healer Annora on this show.)

“There are definite similar💃ities between storylines,” he says. “I’m not the first person to call ‘Sons of Anarchy’ ‘Hamlet’ in leathers, but it was very much a Jacobean tragedy and this is absolutelꦓy of that world in terms of body count and retribution.”

And even after seven seasons playing a vampire on “True Blood,” Moyer admits he’s still squeamish about gory scenes — as is his “Blood” co-star/wife Anna Paquin, who traveled with him to Wales along wit🔜h their 3-year-old twins.

❀“I’m an utter wuss,” he says. “We just had a screening of the pilot on Saturday night … and there’s moments where I still have to scratch my jeans for a minute and look down. Anna was watching it for the first time and she was literally squeezing the blood out of my hand.”
