To mark the occasion, Moore put her own spin on the classic film.

“Jules would have loved Brat Girl Summer. Happy 39th birthday to #StElmosFire!” Moore captioned an Instagram Reels. The clip featured a video compilation of Moore as her romcom character Jules — a member of the seven-person group which later became known as the "Brat Pack."

The film also starred Emilio Estevez, Andrew McCarthy, Rob Lowe, Ally Sheedy and Judd Nelson.

In a 1985 New York magazine article by David Blum, he decided to dub the then-teen actors the “Brat Pack” and the name has stuck for decades.

However, the young stars weren’t initially a fan of the nickname.

"None of us really liked the idea of being called 'brats,' or that we weren't professionals or didn't take our work seriously," Moore recently told Entertainment Weekly. "It was such an interesting, curious thing. We all had different experiences. [The Brat Pack] was very impactful for Andrew, and shifted the direction of his career.”

The gang recently got back together in New York City to support McCarthy, 61, at the Tribeca Film Festival where his documentary BRATS debuted at the OKX Theater at Borough of Manhattan Community College on June 7.

One of the things Moore discussed in the documentary was how St. Elmo's Fire director Joel Schumacherstuck his neck out for me.”

“They could have easily just found someone else,” she said in the film.

“Because it’s not like I had any box-office draw. You know, we were all just beginning. I didn’t have anything to really warrant him sticking by me.”

"It had professional ramifications," he said. “The public embraced us, but the business reacted to it in a negative way."

Perhaps all is forgiven, as in Moore’s Instagram post on Friday, she celebrated the St. Elmo’s Fire anniversary with an interesting music selection — Charli XCX’s song “365,” from her sixth studio album Brat.
