Miriam Margoyles has some choice words for Steve Martin.

In her new memoir Oh Miriam!: Stories From An Extraordinary Life, the British actress recalled her not-so-nice interactions with Martin while filming the 1986 Little Shop of Horrors, in which Martin played dentist Orin Scrivello and Margoyles played his assistant, the Dental Nurse.

The two performed together in the musical number “Dentist!,” in which Martin’s Scrivello punched Margoyles’ 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 – perhaps he was method acting – and came home grumpy with a splitting headache,” she wrote, per HuffPost UK, adding, “let it not be said that I have never suffered in the name of art.”

While she admitted that Martin was “undeniably brilliant,” she also claimed that he was “horrid” to her.

Decider reached out to Martin’s representative for comment, but did not hear back in time of publication.

Other than her role in Little Shop, Margoyles is best known for her role as Professor Pomona Sprout in both Harry Potter and the Chamber of Secrets and Harry Potter and the Deathly Hallows — Part 2.

According to HuffPost UK, Martin is not the first victim of Margoyles’ wrath. The actress has previously deemed Arnold Schwarzenegger as “a very boring man” and John Cleese as a “puny tadpole of a person.”

However, Margoyles raved about Steve Buscemi in the new memoir. She starred alongside the actor in the 1993 dark comedy Ed and His Dead Mother, and wrote that he is a “brilliant actor,” and that they had “a delightful rapport.”

“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,” she added.

The 1986 adaptation of Little Shop of Horrors is streaming on Max.
