Billy Eichner is already in the Christmas spirit for next year.

The “Mufasa: The Lion King” star said that he recently sold a script to Amazon for a Christmas comedy.

The Queens native, 46, is co-writing the upcoming project with celebrated playwright and “Sister Act” screenwriter Paul Rudnick.

Eichner will also co-star in it.

“It’s about a mother-son duo from New York City who go up to spend Christmas with my character’s creepy brother in a charming small town in Vermont,” Eichner explained.

(If he needs casting ideas, we’re thinking of Jessica Lange, Meryl Streep, Kathy Bates or Helen Mirren as the mom.)

The “Parks and Recreation” alum chatted with us at the Broadway opening of “Gypsy” and happily dispelled a commonly held misconception about his bar mitzvah theme.

“It has been widely reported that it was Madonna-themed,” he revealed. “That’s slightly inaccurate. It was technically Broadway meets pop music because I couldn’t decide.”

He added: “So on one side of the DJ booth there was a life-size airbrushed portrait of Madonna and on the other side of the DJ booth was a similarly life-size airbrushed picture of ‘The Phantom of the Opera.’ ”

So judging by the theme, did his parents know at the time that their son was gay?

“I think they knew before that. I think they knew when I was 5 years old and spinning thinking I was ‘Wonder Woman,’ ” he opined.

Other celebs at the splashy Broadway opening included Lea Michele, Jonathan Groff, Laverne Cox, Iman, Rosie Perez and “Frasier” star David Hyde Pierce.

Also at the show, director George C. Wolfe shared that he doesn’t agree with W.C. Fields adage never to work with dogs or kids.

His latest production, “Gypsy,” has both.

“All of them have been great,” he enthused, “so he was wrong!”
