She said about her hatred of filming with the Terminator bodybuilder: "No, I didn't enjoy it at all. I thought he was full of himself and [inappropriate].
"Not [with] me, thankfully, but anybody else that was young and pretty, he felt they were fair game. That was what it was like then."
In 2016, she labelled the former Governor of California a "pig of a man".
She told the Guardian: "Although he was relatively professional with me – because he didn't like me – he was awfully [inappropriate] with women he was interested in.
"He thought a lot of himself, but I wasn't surprised: he was a bodybuilder from Austria who went on to become a worldwide star."
She is the only person from the cast to have publicly made such claims, and they have not been corroborated by any other individuals from End of Days.
Schwarzenegger has not responded to Margolyes' 2016 allegations.
He once admitted he "behaved badly sometimes" while working as an actor, but insisted "a lot of" the claims were untrue.
In 2003, the Los Angeles Times published an interview with six women who claimed Schwarzenegger had inappropriately touched them without their consent.
The women alleged that one incident took place in 1970s, two in the 1980s, two in the 1990s and one in 2000.
Margolyes said about the alleged farting incident: "I got my throat slit with a glass table at the end [of the film], and I remember Schwarzenegger farting right in my face as I lay on the floor trying not to move.
"I shouted: 'F*** you, Arnie!' I was very angry."
