Miriam Margolyes Says Steve Martin Was 'Horrid' to Her on 'Little Shop of Horrors' Set

The 'Harry Potter' actress writes that her costar was "undeniably brilliant, but horrid to me," in her new memoir

Miriam Margolyes doesn’t appear to be the biggest fan of her former costar Steve Martin.

The pair both starred in the 1986 cult classic Little Shop of Horrors, with Martin, 78, playing dentist Orin Scrivell and Margolyes one of his dental nurses.

Recalling their experience on set together, Margolyes branded the Only Murders in the Building star “unlovely” and “horrid” in her new memoir Oh Miriam: Stories From An Extraordinary Life.

In the movie, Margolyes and Martin perform the musical number “Dentist!," which sees Margolyes’ character punched in the face by Martin’s character Orin, who also appears to enjoy opening doors into his assistant.

Per the Huffington Post, the Harry Potter actress writes in her book, “I was hit all day by doors opening in my face; repeatedly punched, slapped and knocked down by an unlovely and unapologetic Steve Martin — perhaps he was method acting — and came home grumpy with a splitting headache. Let it not be said that I have never suffered in the name of art.”

She added that Martin was “undeniably brilliant, but horrid to me."

PEOPLE has reached out to Martin's rep for comment.

Margolyes also went on to compare Martin to her Ed And His Dead Mother costar Steve Buscemi, calling the 65-year-old “unerringly sweet” and revealing he “knocked spots off Steve Martin.”

Last year, Margolyes weighed in on working with another famous face — Arnold Schwarzenegger — and claimed that the actor “was actually quite rude,” and even “deliberately” farted in her face while filming their 1999 flick End of Days.

She told news.com.au's I've Got News for You podcast, "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.”

Margolyes added that she "didn't care for" for the former governor of California, 76, as "he's a bit too full of himself.”

In a cover story for British Vogue's Pride July issue earlier this year, Margolyes opened up about her career, upbringing and coming out as a lesbian in 1966.

"I think gay people are very lucky, because we are not conventional, we are a group slightly apart," she told the publication. "It gives us an edge. We’re good artists, we’re good musicians."

"And I like being gay. I wouldn’t want to be straight for anything," Margolyes added.

The British-Australian star continued that she's "never had any shame about being gay or anything really." "I knew it wasn’t criminal because it was me. I couldn’t be criminal," Margolyes explained.

The actress' second memoir is due in January.
