Here are some youtube videos of Johnny Depp reading letters from his correspondence with Hunter S. Thompson: 1, 2, 3. In particular, Mr. Depp admits,
If I do a remotely decent job of portraying you, you know there’s a very good chance you’ll hate me for the rest of your life.Here is an interview that youtube suggested I watch after these videos: Hunter S. Thompson and David Letterman (1988).
I am astonished at the degree of faithfulness that Johnny Depp achieved with his performance. And I hope that Hunter S. Thompson does not hate it.
