Harry Potter’s Miriam Margolyes bashes ‘horrid’ Steve Martin

Steve Martin is accused of being a little shop of horrors on set.

According Miriam Margolyes, the 78-year-old “Only Murders in the Building” actor was “horrid” and a “c—t” to her when they starred opposite one another on the set of Frank Oz’s “Little Shop of Horrors” in 1986.

In the movie musical, that is currently playing off-Broadway, Martin played the role psycho dentist Orin Scrivello, who had a penchant for blood and pain, while Margoyles appeared in all-white as his nurse and assistant.

In her new memoir, “Oh Miriam! Stories from an Extraordinary Life,” the 82-year-old actress recalled her scenes with Martin as being rather physically painful. She suspected the comedian perhaps got a little too into his character.

“During my only musical number (‘Dentist!’) I was hit all day by doors opening in my face; repeatedly punched, slapped, and knocked down by an unlovely and unapologetic Steve Martin,” Margolyes writes. “Perhaps he was method acting – and [I] came home grumpy with a splitting headache.”

The Post has reached out to Martin’s representative for comment.

Margolyes, best known these days for playing Professor Sprout in the “Harry Potter” film franchise, noted that Martin was great at his craft and a “perfectionist,” but that didn’t make her time working with him any better.

“He was incredibly unfriendly because he was a perfectionist,” she continued. “He was an artist and all he was interested in was getting the comic moment right, and he was correct to do that, but he should have included me,” she told news.com.au in a recent interview. “I didn’t enjoy it and I had a splitting headache at the end of the day.”

In her memoir, Margolyes concluded, “Let it not be said that I have never suffered in the name of art. Steve was undeniably brilliant, but horrid to me. He was a c–t, that’s all I can tell you.”

This isn’t the first time Margolyes has had a problem with a high-profile actor in Hollywood.

During an interview on the “I’ve Got News For You” podcast in July 2022, Margolyes made a big stink about her time filming the 1999 horror movie “End of Days.”

She claimed the film’s star Arnold Schwarzenegger, 76, “was actually quite rude” during the film’s shoot and deliberately farted in her face.

“[I] didn’t care for him; he’s a bit too full of himself,” Margolyes said about the former California governor. “He’s a Republican, which I don’t like. He farted in my face. Now, I fart, of course I do – but I don’t fart in people’s faces. He did it deliberately, right in my face.”

Describing the biblical action flick, she recalled: “I was playing Satan’s sister, and he was killing me, so he had me in a position where I couldn’t escape and lying on the floor. And he just farted.”

Schwarzenegger never commented on the allegation.

Despite some terrible experiences working on set, Margolyes did have happy memories remembering her time with Steve Buscemi on 1993’s “Ed And His Dead Mother.”

“Steve Buscemi is a brilliant actor and we had a delightful rapport,” Margolyes said, according to Variety. “For somebody who’s being terrorized by me in the form of a murderous living corpse, he was unerringly sweet – knocked spots off Steve Martin.”
