"I'm pretty sure he came and saw everything I ever did on stage both in London and New York. He didn't have to do that. I know other people who've been friends with him for much much longer than I have and they all say 'if you call Alan, it doesn't matter where in the world he is or how busy he is with what he's doing, he'll get back to you within a day,'" he added.
Watson shared on Facebook: "I'm very sad to hear about Alan today. I feel so lucky to have worked and spent time with such a special man and actor. I'll really miss our conversations. RIP Alan. We love you."

RIP."
