The two-time Academy Award nominated star was asked about the moment she realised she had made it as an actor.

‘And I was eight feet tall, on a billboard in Time Square, and I thought, “Wow, I think I’ve made it,”‘ Margot added.

The show she was likely referring to was her first break in the drama Pan Am – based on Pan American World Airways – where she starred alongside Christina Ricci.

Special moment: She recalled, ‘One day when I moved to America and I was in Times Square in New York City and there was a giant billboard of a TV show that I was shooting. And I was eight feet tall, on a billboard in Time Square, and I thought, “Wow, I think I’ve made it”
