Haddock really entered the American pop culture mainstream when she landed the starring role of Lucrezia Donati in Da Vinci's Demons.
Starring alongside Tom Riley, who plays the series' title character, Haddock quickly became a fan favorite, leading to her first experience sitting for a slew of interviews, panels and appearances. Unsurprisingly, she was super-stoked to get the gig, telling Couch TV at New York Comic-Con 2014 that she kept her fingers crossed after auditioning. She initially thought she was passed over for the role, due to a slight misunderstanding of the American vernacular.
Fortunately, it all worked out, and Haddock's work as Donati marked the first time she truly hit it big on the international small screen.
