Never let it be said that Arnold Schwarzenegger doesn't give it his all when he performs - but for British-Australian actress Miriam Margolyes, he could have definitely held back a bit. 

While guesting on news.com.au's I've Got News For You podcast, Margolyes recounted a crude, yet amusing story about the time she worked with Arnold on the set of the 1999 action/horror film End of Days. Calling him her "least favorite co-star," Margolyes said: 

"He's a bit too full of himself and I don't care for him at all."

Other than him being a "Republican," her real grudge came from something the former California Governor did to her in between takes.

"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." 

In the film End of Days, Schwarzenegger plays a broken-down security specialist who must save a young woman (Robin Tunney) from the advances of the Devil (Gabriel Byrne) before the start of the new millennium. 

"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."

Margolyes did let out a snicker or two during the story. Then she continued, 

"It wasn't on film, it was in one of the pauses, but I haven't forgiven him for it."

Funnily enough, a story about a 6'1" Austrian bodybuilder cracking one off in a sweet older actress's maw is far scarier than anything we saw in End of Days. Stay classy, Arnold
