It seems like your message is a bit jumbled up. If you are asking which book is 'new, thin, and dirty', it could be "The Adventures of Tom Sawyer" since a well-read book often becomes thin and dirty over time.
As for washing your hands, I recommend washing them with soap and water for at least 20 seconds, as this is important for maintaining hygiene and preventing the spread of germs.
I'm not sure about the film with the actor you mentioned as it's not clear in your message. Could you please provide more context or clarify your question?
