Well, then I started walking along Charing Cross street and started checking bookstores randomly. Can you believe?, I actually found the book I was looking for. It was, "An Actor prepares" by Konstantin Stanislavski. After I found the book and just couldn't resist to start reading it. I found an aptly tranquil place in "Café Vergnano 1882" (62, Charing Cross street) near Lancaster Square, and started reading.
Now, you may wonder, what am I getting at. What do I want to convey? Probably nothing. It was an amazingly surrealistic experience. It was as if, I had gone back some 50 years in time. I was browsing through all the old books in every possible bookshop. I was sitting in a café which commenced its operations in 1882. Reading Stanislavski was a great experience too. The person who made "Method Acting" so popular. The person revered by so many actors, like Marlon Brando, James Dean, Al Pacino and Lee Strasberg.
