Emilia Clarke in Triassic Attack (2010)

“Before she was transformed into an international superstar as a result of playing Daenerys Targaryen, Clarke had virtually no on-camera experience as an actress, bringing to the table one episode of a TV melodrama (Doctors) and one SyFy Original Movie. Fortunately, that movie— Triassic Attack — provided her with the opportunity to say, ‘Why, yes, I do have experience working with giant reptilian beasts,’ which takes you surprisingly far in the world of Game of Thrones.”
