The aged Lord of the Crossing, Walder Frey oversees his massive brood—it’s a common jest that he can field an army out of his pants—and the chief crossing of the Green Fork that they control. Ninety-one years old, he has had many wives, many legitimate children, and not a few illegitimate ones… and as of the first novel, he has a new, young bride whom he is eager to get more children one despite his growing infirmity. He is also called the Late Lord Frey, for his late appearance at the Battle of the Trident after all the fighting was done. Lord Walder is a venal, suspicious, and ambitious man.
The actor cast in the role is almost twenty-five years younger than the character as described in the novels, which raises the question as to whether they will youthen old Lord Walder or, alternatively, use performance and make-up to make him seem older than his true age.
