Emmanuel, who was also in “Game of Thrones,” told outlet Story + Rain that before she did a screen test with Vin Diesel, “I had to picture me and Vin at the screen test, exactly the same size, physically. Vin is a huge action star; he’s a big guy. By comparison, I’m just this little person from [the UK town of] Southend-on-Sea! . . . I imagined myself to be exactly the same thing. And it helped me carry myself slightly differently.”
