Margaery Tyrell — Blake Lively
In Thrones, the stunning Natalie Dormer does an excellent job as Margaery Tyrell — the young, powerful Queen that ultimately becomes one of Cersei’s main adversaries. With Angelina Jolie already set to star as Cersei, who better than Blake Lively to portray her main rival? Like Dormer, Lively has a natural grace about her. She is very intelligent and determined — not to mention she won?t stand to take Cersei’s heavy-handed ways.
