Sigourney Weaver made sure to keep her distance from Harry Connick Jr. while they were shooting the 1995 movie Copycat.

Directed by Jon Amiel, the psychological thriller stars Weaver as a forensic psychologist who becomes agoraphobic after a near-fatal encounter with one of her subjects — Connick’s psychotic serial killer Daryll Lee Cullum — at the beginning of the film. But Connick recently revealed that, much like her character, Weaver continued to steer clear of him even when the cameras weren’t rolling.

"Sigourney Weaver, she's so unbelievable. She wouldn't talk to me," he recalled on a recent episode of SiriusXM’s The Jess Cagle Show With Julia Cunningham. "I didn't meet her till the premiere. She would not — every time I came around, she went the other way. She was like, 'I don't want to be around that guy!'"

The singer joked that the experience of being avoided made him remember "what it was like to be in high school."

In the film, Det. M.J. Monahan (Holly Hunter) and her partner Ruben Goetz (Dermot Mulroney) tap Weaver’s psychologist character, Dr. Helen Hudson, to help solve a series of murders that seem to have been inspired by famous serial killers. Along the way, the story reveals that Daryll is playing a much larger role in the case than they thought.

While visiting The Jess Cagle Show, Connick recalled landing the part of the obsessed psychopath just as he was thinking about taking a break from acting. "My manager said, ‘There's a guy named Jon Amiel. He's a British director. He's doing a film called Copycat,'" the singer-actor said. "I didn't know anything about it. She goes, 'Why don't you just go meet him?' I said okay."

Connick also recalled that at the audition Amiel asked him about his knowledge of serial killers as well as his New Orleans accent.

"I started, like, giving him some Southern expressions and he said, 'Okay, thank you,' and I'm like, 'Oh, well, there's another one!'" Connick said. "Then my manager calls me like an hour later and says, 'He wants you for the role.' And I'm thinking, like, 'What did I possibly do to convince this guy that I could play that guy?'"
