Mark Ruffalo hulks over to City Hall in fight over historic Upper West Side church

A church fight is Ruffalo-ing feathers at City Hall.

Marvel actor Mark Ruffalo smashed his Hulk-sized star power into the corridors of New York City’s government offices Monday for a secret closed-door meeting.

Ruffalo and fellow actor Fisher Stevens held a covert confab with First Deputy Mayor Maria Torres-Springer as part of a long-running, celebrity-backed fight to stop the demolition of West-Park Presbyterian Church, a 19th-century church on the Upper West Side, sources confirmed to The Post.

The architecture aficionado thespians made a brief in Room 9, the City Hall press room, where they posed in front of Post and New York Daily News front pages featuring big headlines made since Mayor Eric Adams took office. 

“Holy s–t, is that ‘Short Circuit’s’ Fisher Stevens?” gasped one reporter, referring to the 1986 comedy in which the white actor regretfully donned brownface to play an Indian character.

“I’m starstruck,” another said as Ruffalo toured the building.

Besides reporters’ rumblings, the Ruffalo visit otherwise drew very little hullabaloo inside City Hall itself.

The closed-door meeting with Torres-Springer covered a heated dispute between preservationists and developers over the fate of West-Park Presbyterian Church, said City Hall officials and Councilwoman Gale Brewer (D-Manhattan), who also attended the summit.

As the West 86th Street church’s congregation dwindled to a mere dozen faithful, they sought to sell the historic structure to a developer to avoid a $50 million restoration bill.

To do so, they submitted a “hardship” application — which they eventually withdrew — to strip its landmark status and clear the way for demolition.

The move prompted a lawsuit and a fight by a local nonprofit — supported by a laundry list of stars, including Ruffalo, Stevens, Matt Damon, Amy Schumer and Matt Dillon — to raise funds to preserve the site.

Brewer, who helped landmark the building, disputed that it is beyond repair.

“The building is not falling apart,” she said. “I was there two nights ago. Beautiful, not falling apart. It does need money for the roof, which we have, and then we can take the scaffolding off.

“We could use some help with the Presbyterian, that’s why we were here today.”

The Center at West Park’s executive director Debby Hirshman told The Post they’re committed to preserving the building.

“We have reflected that this landmark building is safe and economically viable to support itself and its maintenance,” she said.

“[It] is an anchor to upper Manhattan.”

City Hall spokeswoman Liz Garcia confirmed to The Post that the celebs met with only Torres-Springer, adding that officials are working with both parties to find a solution.

“He was so nice, we weren’t expecting an Avenger to come into the office,” Garcia said about Ruffalo.
