Jessica Chastain may have very well found something even more embarrassing than getting naked or doing a love scene for a movie: filming (multiple) visits to the dreaded gynecologist in her new espionage thriller “The Debt.”

“Those were really horrible to shoot. We shot the scenes in chronological order of the doctor sequence but it was my last week of filming and for a week I had to lie on that table,” Chastain told FOX411’s Pop Tarts column. “I’m not naked, I’m wearing a gown, but still it was just so humiliating to be in that position all day long.”

John Madden’s “The Debt,” which opens in theaters this week, begins in 1997 when legendary, retired Mossad agents Rachel (Helen Mirren) and Stefan (Tom Wilkinson) are faced with devastating news about their former colleague, David. All three have been hailed as heroes due to their incredibly dangerous 1966 mission, when the trio (played by Chastain, Marton Csokas and Sam Worthington) successfully sought revenge on Nazi war criminal Vogel in East Berlin. But 31 years later, the painful, untold truth behind the escapade is about to be unraveled.

The film material also begs the question: should war criminals still be tried if discovered long after their crimes have been committed?

“I think war criminals from any nation should be called out because the people who suffered – Stalin – and the people who died under Stalin, God damn it,” Helen Mirren told Tarts. “You’re not allowed to say that, are you? But God damn Stalin! He was never brought to justice.”

Co-star Sam Worthington agreed with Mirren’s sentiments.

“You have to be responsible for your actions. Whether it’s a Nazi war criminal being brought out because he slaughtered children and experimented on people, or the fact that these people end up with their plan going sour, they hold on to a secret and have this burden,” he said. “You’ve got to own up to your actions and your mistakes.”

And just because Worthington is now a household Hollywood name thanks to leading roles in “Avatar” and “Clash of the Titans,” it doesn’t mean buddies in his native of Australia won’t let him forget his former career – construction and bricklaying.

“I’ve got mates that still make me dig a hole when I’m back in Australia – they tell me, ‘don’t get too big for your boots,” he added. “But I go under the radar pretty easily. I get mistaken for Zach Galifianakis all the time, so that’s a bit hard but I just sign his name anyway and it’s fine. But I go under the radar, so I don’t have any bad, fanatical fan experiences, which is good.”
