Real live vs. Characters:
Cersei and Tyrion Lannister loathe each other. In real life, Lena Headey and Peter Dinklage are very close friends and live together during filming. And Thomas Brodie-Sangster, who plays the 13-year-old character Jojen Reed, was 22 when cast in the role.
Could you believe it? Not everything is just acting. Maester Aemon Targaryen of the Night’s Watch is revealed to be blind in the novels. He is played by Peter Vaughan, who is legally partially blind himself.
