Sometimes, all it takes is one role to catapult an actor from relative anonymity to worldwide notoriety. For Emily Blunt, that role was playing Emily, the sassy British assistant to Meryl Streep's Miranda Priestly in "The Devil Wears Prada."

As Blunt told Vulture, she definitely considers the film her big break: "'Devil' was the film everyone loved and saw, so it had a huge impact on my career. It helped reveal a certain part of me; I wasn't just the ingenue or the English rose. It helped me be seen as a character actor, which is what I'd always wanted."

In fact, the role was so iconic, it is still winning her new parts to this day. As Rob Marshall, director of "Mary Poppins Returns" and "Into the Woods" told Vanity Fair, seeing her in "The Devil Wears Prada" was all it took to intrigue him. "She reminded me immediately of a young Maggie Smith because of the humor, the acting chops, the vulnerability," he said. "I see her having an incredibly long career because of the uniqueness of her extraordinary talent. It transcends beauty and looks and age."
