In 2005, it was revealed that Law had cheated on Miller with their children’s nanny. He issued a public apology to her at the time.
“That was one of the most challenging moments I hope I’ll ever have to experience,” the Golden Globe-nominated actor told The Daily Beast.
“Because with that level of public heartbreak, to have to get out of a bed let alone stand in front of 800 people every night, it’s just the last thing you want to do.
“It was really hard. And the other thing was, it was at the height of all that paparazzi madness, and in London where there was an epidemic of bad behaviour. They knew where I would be every night.”
While Miller still managed to receive critical raves for her performance, she said she struggled to remember the details of her life during that time.
“There’s a whole six weeks of that experience that I don’t remember. I have no recollection of it,” she said.
“People who came to see me said we had dinner, and I don’t remember. I was in so much shock over it all. And I’d really just begun. I was only 23. But if you get through that, you feel like you can get through anything.”
In 2011, the now-defunct tabloid The News of the World admitted liability over the hacking of Miller’s phone during the scandal, and paid her £100,000 – the highest invasion-of-privacy settlement at the time.
“It was a long battle, and I think I was really paranoid,” Miller said. “There was so much noise that it was hard to think straight and focus on my work, which I always took very seriously. It ate everything else. I look back on it and wonder how I did get through it—but I did.”
Miller has gone on to become one of the most respected actors of her generation, appearing in critically acclaimed dramas including The Girl, Foxcatcher and American Woman.
She next stars in forthcoming drama Wander Darkly, opposite Diego Luna. The film is released on 11 December.
