For some children, spending time in their parents' place of work can be a drag. ForMary McCartney, though, going to work with mom and dad meant spending time in one of the most legendary recording studios of all time: Abbey Road Studios.

It makes sense, then, that it’s McCartney, daughter ofBeatlePaul McCartney, who is bringing the London locale’s storied history to the silver screen in hernew documentaryIf These Walls Could Sing, which will hit Disney+ on Dec. 16.

“I had no idea that it was 90 years old. I’ve grown up going my whole life, but I never knew all the facts,” the photographer, filmmaker and cookbook author, 53, told PEOPLE at the film’s Wednesday night premiere in N.Y.C. “So I’ve really immersed myself in it and really dissected the stories and I think there’s some surprises in there.”

Sir Paul McCartney and Mary McCartney attend the UK Premiere of “The Beatles: Get Back” at Cineworld Empire on November 16, 2021 in London, England.

“I love the picture of my mom going over the zebra crossing. She had a little pony in London. That’s one of the reasons I wanted to do [the film],” she said. “I snuck her into it a few times. There’s an homage to her. She’s my inspiration.”

Though Linda died of cancer in 1998 at age 56, McCartney was able to get dad Paul, 80, on board, who shared with her the sort of insight only a former Beatle like himself could know.

“I was with him and I was like, ‘I’m going to make this documentary about the history of Abbey Road,’ and he would just sort of give me little tips. It was good! He was mulling it over and he sort of told me little anecdotes,” she said.

The star recalled one interview in particular with the “Band on the Run” singer, and said he was eager to talk not only about the studio itself, but about the people who worked there.

“He was keen to talk about how the people there had helped them—staff, people behind the scenes, engineers,” she said. “He feels passionate about it. I think in the documentary you see how passionate he is about it.”

British filmmaker Mary McCartney arrives for the premiere of “If These Walls Could Sing,” at the Metrograph in New York City on December 7, 2022.

Though McCartney said she put most of the “juicy stuff” in the documentary, there were some fun details left on the cutting room floor — like the ways in which Linda found some unexpected benefits in Abbey Road.

The studio has famously played host to everyone from The Beatles andLittle RichardtoPink Floyd, theSpice GirlsandLady Gaga. In more recent years, it’s also become a destination for film scoring; movies likeBlack Pantherand many of theStar WarsandHarry Potterscores were recorded there.

If These Walls Could Singincorporates vintage footage of artists recording, as well as new interviews with McCartney,Elton John,Ringo Starr,Noel Gallagher,Roger Watersand more.
