Jon Cryer isn’t mincing words when talking about his Pretty in Pink costar Andrew McCarthy.

The Hot Shots! star, 59, participated in McCarthy’s documentary film BRATS , about the group of actors dubbed the “Brat Pack” in a 1985 New York Magazine article about young Hollywood stars in the 1980s who made coming-of-age films at the height of their fame.

During a Q&A session after the film premiered at the Tribeca Film Festival in New York City on Friday, June 7, Cryer got honest about what he thought of McCarthy, 61, when they starred together in the 1986 rom-com Pretty in Pink, alongside Molly Ringwald.

“When we had done Pretty in Pink together, we did not get along because he was a d—,” Cryer —who played Ringwald’s character Andie’s best friend Duckie in the film — said of McCarthy.

“That’s very true,” said McCarthy — who played Blane, a rich but sensitive playboy — about Andie’s dilemma, as both teenagers harbored feelings for her.

Demi Moore, who starred opposite McCarthy in St. Elmo’s Fire, disagreed with Cryer at the Q&A.

“Well I didn’t think he was a d—,” the Ghost star said, to which Cryer replied: “Well he wasn’t a d— to you.”

Moore, 61, agreed and elaborated on why she decided to participate in BRATS, which McCarthy wrote and directed.

“My heart swelled when I got that call [from McCarthy to participate], and [I felt] just a flood of joy and I feel like I hadn’t thought about the effects of that time,” she said, adding that many of the actors who were considered part of the Brat Pack at the time “lost each other” over those years because they felt pressure to build a name for themselves on their own.

As for Cryer and McCarthy, they mended their differences in a greenroom at The View, in 2012, and they spoke about that moment at the BRATS premiere.

“It was a lovely moment,” Cryer said, and McCarthy confirmed that he apologized to his former costar.

“A little. But it was lovely because it was like within a moment, it was just so clear that we were teenagers and that does not, that in no way defines who we are now and it was just so lovely. It was immediately warm,” the Two and a Half Men star said of their conversation.
