Andrew McCarthy Wore a Wig in “Pretty in Pink — ”and Other Bombshells from the Hulu “Brats ”Documentary

Andrew McCarthy's new Hulu documentary 'Brats' tracks the rise of the young stars crushing it in Hollywood in the '80s

The "Brat Pack" were the Timothée Chalamet, Zendaya, and Sydney Sweeney of their day — except they were even more famous.

They also truly turned the movie industry on its head, once studios realized what a draw movies for teenagers were. "Suddenly there was a movie for young people every Friday," Andrew McCarthy tells PEOPLE of their impact on society.

In his new documentary Brats (available to stream on Hulu June 13), McCarthy takes a walk down memory lane with fellow Packers like Emilio Estevez, Rob Lowe, Ally Sheedy, Jon Cryer and Demi Moore to talk about those days, the Brat Pack nickname, and where they're all at now. Naturally, some fun secrets were revealed during the making of the doc — like who had a crush on who, and who didn't make the Brat Pack list!

Read below for some of the biggest bombshells from Brats.

Andrew McCarthy Wore a Wig in the Final Pretty in Pink Scene

In the final prom scene, Andrew McCarthy's character admits to Molly Ringwald's that he does in fact love her. A romantic kiss in the rain ensues, all to the song "If You Leave," by Orchestral Maneuvers in the Dark. But if you look closely, you MIGHT see that McCarthy's hair looks different in this scene than it does in the rest of the film. That's because in the original version, they don't get back together — Molly Ringwald's Andie instead dances the night away with her bestie Duckie (Jon Cryer.) Test audiences hated that ending. "They wanted the fairytale ending," McCarthy says. So they reshot it with the happy couple smooching, but McCarthy had already cut his hair off for another role. So he was wearing a piece. "It wasn't a very good wig," he says with a laugh.

Demi Moore Had a Sober Coach on the St. Elmo's Fire Set

When McCarthy caught up with Demi Moore at her home in Los Angeles, she opened up about being taken care of by St. Elmo's Fire director Joel Schumacher. “They paid to have a sober companion with me 24/7, during the whole shooting," she tells him, adding that Schumacher “stuck his neck out for me." "They could have easily just found someone else," she says, "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.”

Ally Sheedy Thought McCarthy Was 'Aloof,' He Says He Had a Crush on Her

During his in-person catch up with Ally Sheedy, 61, who was McCarthy's costar in St. Elmo's Fire, he reveals he used to have a thing for her. "I had a little crush on you back in the day," he says. "You did not!" Sheedy replies. "I was so scared, I was so busy being aloof," he adds, to which she confirms, "Yes you were aloof!" She wasn't the only one who thought so: During the Brats screening and panel at the Tribeca Film Festival on June 7, Cryer said that McCarthy was a "bit of a dick" when they worked together, but later discovered he'd been going through some personal things at the time. "Now we have nothing but love," Cryer said.

Molly Ringwald Didn't Want to Participate — Here's Why

When McCarthy was interviewing Cryer, Cryer asked if he'd spoken to Ringwald about the Brat Pack. "She said she'd think about it but that she'd probably like to keep looking forward," McCarthy says. Cryer understood: "We all want to be [treated] as actors," he says. Regarding the term the Brat Pack and being known for her three John Hughes movies (Sixteen Candles, The Breakfast Club and Pretty in Pink), Ringwald once told PEOPLE that she looked back on those films fondly. "They'll always have a special place in my heart," she said.

Jon Cryer Says He Wasn't Cool Enough to be a Brat Packer — But He DID Date Demi Moore

Jon Cryer, the actor who played Duckie in Pretty in Pink (and went on to massive success on Two and a Half Men) says that he was never part of the Brat Pack because he wasn't cool enough. The film shows an old interview where he's asked if he was part of it, and he replies, "I hope not." Still, he was cool enough to go out with Moore: "We dated for a short time while we were working on No Small Affair, but I guess our particular affair was, in fact, pretty small," he told PEOPLE.

Emilio Estevez Refused to Work with Other Brat Packers After The Breakfast Club

When McCarthy meets up with Estevez at his home, it was the first time they'd hung out in over 35 years — however, around the height of their stardom, they were supposed to do another movie together but Estevez explained he didn't want to work with McCarthy after the "Brat Pack" article came out. "We were kryptonite to each other," Estevez says. "We all scattered for the hills." The two talk about the ramifications that the nickname the "Brat Pack" had on their careers, noting that it stigmatized them, but they've since let it go. Still, "Who wants to be labeled?" McCarthy asks.

The Instrumental Love Theme from St. Elmo's Fire Made It to Top of the Charts

It was a saxophone-heavy instrumental that played in the background, as Rob Lowe and Mare Winningham's characters in St. Elmo' Fire finally got together — and it was a hit! Of course these films were all accompanied by popular soundtracks, and the cast of St. Elmo's Fire were actually in the music video for John Parr's theme song ("St. Elmo's Fire: Man In Motion"), which peaked at No. 1. But no one expected the sexy instrumental, written by David Foster, to also rise up the charts to No. 15 on the Billboard 100.

Lea Thompson Says She Wanted to Be in the Brat Pack Club But Wasn't — and Neither Was Tom Cruise

Lea Thompson was certainly Brat Pack-adjacent: She starred in the movie Some Kind of Wonderful alongside Eric Stoltz and Mary Stuart Masterson and it was a John Hughes film — but it came out in 1987, a year after Pretty in Pink, and somehow she was never grouped with the OG Packers. "I wished I was in the club," she tells McCarthy, adding that all the people that were in it were so cool. While she starred alongside Tom Cruise in the 1983 movie All the Right Moves — and Cruise also came up in the same era, in films like Risky Business and The Outsiders, and then in Top Gun and Cocktail in 1986 — he wasn't part of their crowd. "He did his own thing," she says.
