The opening credits of “The Perfect Couple” are palpably ecstatic, but they almost never happened.

Netflix’s new whodunit begins each episode with a cheerful, choreographed dance, but the cast once nearly rebelled against the sequence, Variety reported Thursday.

The series, based on the novel of the same name by Elin Hilderbrand, follows a wealthy family forced to postpone a wedding in Nantucket, Massachusetts, when the maid of honor is found dead just before her best friend’s wedding.

“I think I wanted to do something where we’re telling the audience, ‘This is going to be fun,'” director Susanne Bier told Variety ahead of the show’s Los Angeles premiere on Wednesday. “I think this time (period) is a little bleak and I wanted to do something with a lot of life.”

Bier opted for a flash mob-style dance evening on the beach to Meghan Trainor’s song “Criminals.”

The stars, however, were just as skeptical as the characters in the murder mystery. Several cast members apparently hated the idea and started a WhatsApp group chat in the hopes of ruining the dance.

“Everyone in that group said they didn’t want to do this because we just didn’t get it,” actor Meghann Fahy told Variety. “I have a really, really hard time learning choreography, so I was really nervous about it.”

Nicole Kidman, who plays Greer family matriarch Garrison Winbury, was also unconvinced by the opening. “I didn’t feel like Greer would dance! I felt like Greer would watch,” she told Variety.

“I don’t think any of us could pull off this choreography in these characters,” said Ishaan Khatter, who plays Shooter, the groom’s best man. “We were like, ‘Wait a minute, where does this fit into the picture? This wasn’t part of the brief!'”

Even the show’s producers were reportedly concerned about it. The determined Bier eventually got her way, saying she shot the sequence in less than two hours.

Fahy and Kidman eventually went along with the idea, and choreographer Charm La’Donna was also happy with the “fun day at the beach.” Meanwhile, actor Liev Schreiber never needed convincing, as he had been up for the dance the whole time.

“The whole cast was up in arms about it, except for me, I was already in my trailer practicing the dance moves,” he told Variety. “I just like dancing and I was a little disappointed when it came out that I wasn’t in it anymore, because I thought I did really well.”
