5. Izzy Meikle-Small
Izzy Meikle-Small has an interesting niche in the world of acting, namely in playing younger incarnations of the main characters. She played the childhood version of Carrie Mulligan's character, Kathy H., in Never Let Me Go, as well as Young Estella in Great Expectations - the same production Perdita Weeks appeared in - the Young Ravenna (Charlize Theron's witchy queen) in Snow White and The Huntsman and, most recently, as Young Molly in the film adaptation of Michael Morgupo's Private Peaceful. It seems, however, that she made also made it down to the final two to play Sansa Stark in Game of Thrones. Meilke-Small has since expressed relief at not getting the role based on the amount of flesh it would require her to show. With no offense to Sophie Turner, Sansa has proven so insipid over the last three seasons its difficult to imagine it'd make much difference who was playing her.
