Mark Hamil says ROTJ Luke was his prime
This is not the Luke we remember. As Mark Hamill himself puts it to TF, “It’s shocking to hear Luke say, ‘I know only one truth: it’s time for the Jedi to end’ – the last time we saw him, he was the most optimistic character. He was sort of at the peak of his powers, and you would imagine that he’d then become a Jedi master and train other people and so forth. What has happened to him that has so traumatised him into where he is now?”
