Catherine O’Hara blasts ‘Beetlejuice Beetlejuice’ haters: ‘F–k them’

Catherine O’Hara has no time for the haters who have a problem with the upcoming “Beetlejuice” sequel.

The Canadian acting icon, 70, appeared at CinemaCon in Las Vegas where she and the cast unveiled a new look at “Beetlejuice Beetlejuice.”

The “Home Alone” star headed down to Sin City alongside director Tim Burton and stars Michael Keaton, Justin Theroux, Monica Bellucci and Willem Dafoe.

The forthcoming flick is the follow-up to the 1988 comedy-horror movie that chronicled the mishaps of a deceased couple, whose spirits are being annoyed by the Deetz family that has moved into their home.

“It’s truly very personal and emotional and special,” Burton, 65, gushed to the audience about the project, which is set to debut Sept. 6.

“It’s like a weird big home movie for me,” he continued, according to Entertainment Weekly.

O’Hara then chimed in, adding that the sequel will be both funny and a bit scary for viewers. “And if people don’t like it, then f–k them,” she said on Tuesday.

Keaton, 72, interjected: “I’ll tell you this, it’s really f–king good.”

He famously portrayed the chaotic, black-and-white stripe-wearing “bio-exorcist” named Betelgeuse from the Netherworld who helps out the dead couple, Barbara and Adam Maitland (Geena Davis and Alec Baldwin) to drive out the new family.

“This cast is so good,” the “Batman” star said, noting that he has already watched the second installment. “Everyone is so friggin’ funny. It’s unbelievable how funny these guys are.

“I was very nervous to see if we could pull it off again,” he joked. “But every day got more and more fun.”

Winona Ryder, Jenna Ortega and Burn Gorman also round out the ensemble cast.

O’Hara portrayed Delia Deetz in the film, an artist who moves into the home that is haunted by the Maitlands.

“Beetlejuice is the most f–kin’ fun you can have working,” Keaton previously told Empire magazine. “It’s so fun, it’s so great. And you know what it is? We’re doing it exactly like we did the first movie.”

In November, Dafoe, 68, told Variety that he enjoyed shooting with the cast.

“I haven’t seen any footage yet, but it was fun to do,” the “Poor Things” actor stated at the time. “I play a police officer in the afterlife, so I’m a dead person. And in life I was a B-movie action star, but I had an accident, and that’s what sent me to the other side.”
