Query: The BEST BEST BEST BEST book in the world!!!!!!!!

William Redfield was the BEST actor in the WORLD!!!! And his book "Letters From an Actor" is one of my favorite books in the WORLD!!!! It is funny and fast-reading and I wish it would continue on forever. Anyone who is considering a career in the theatre should definitely read this book. Anyone who isn't considering a career in the theatre should definitely read this book. After you read this book, you feel like you know William Redfield. And everyone, John Gielgud, Richard Burton, etc., were correct when they said that William Redfield and Clem Fowler were the best Guildenstern and Rosencrantz. I recently bought the "Hamlet" DVD with William Redfield. It is one of my favorite movies. And William Redfield and Clem Fowler are the best. And the best parts are the parts with William Redfield, because William Redfield is the best actor in the world!!!!!!!!
