Demi Moore, Andrew McCarthy stage mini 'St. Elmo's Fire' reunion: See the photo

Moore and McCarthy starred in the 1985 film, directed by Joel Schumacher.

Demi Moore reunited with her "St. Elmo's Fire" co-star Andrew McCarthy over the weekend.

McCarthy, 60, took to Instagram on May 21 to share a photo with Moore, also 60, enjoying a mini reunion nearly 40 years after the film's release.

"So great to see (for the first time in years and years) my St. Elmo’s Fire co-star, the wondrous Demi Moore, and catch up for my Brat Pack documentary," McCarthy captioned the snap.

Moore and McCarthy starred in the 1985 film as Julianna "Jules" Van Patten and Kevin Dolenz, respectively. Their castmates included Emilio Estevez, Rob Lowe, Judd Nelson, Ally Sheedy, Andie MacDowell and Mare Winningham.

The film, co-written and directed by Joel Schumacher, who died in 2020, centered on a group of friends adjusting to the realities of adulthood after graduating from college.

Many of the "St. Elmo's Fire" cast, including McCarthy and Moore, were members of a group nicknamed the "Brat Pack" in the '80s, a group of burgeoning actors who frequently starred in coming-of-age films together.
