Fan Casting Olenna Tyrell in A Song of Ice and Fire

Olenna Tyrell, is the widow of Lord Luthor Tyrell and the mother of Mace Tyrell, Lord of Highgarden. Lady Olenna is a small woman the size of a child. The white-haired lady appears wrinkled and wizened. She has soft, spotted hands with gaunt thin fingers. Olenna walks with a cane and claims to be near deaf, but both might be part of her feigning to be more frail than she actually is.
