There’s so much you could ask Stephen Fry. Maybe something about his TV career, from A Bit of Fry and Laurie to Jeeves and Wooster to Blackadder to QI. Perhaps his books – the novels, the memoirs, the classics, how to write poetry.
Maybe something about his illustrious film career, with Wilde the obvious highlight, but which also includes Chariots of Fire, Gosford Park, The Hobbit, Love and Friendship, and Spice World.
