Actor Louis Koo Tin-lok has turned blogger and may now write a book. When Koo attended the premiere of his new movie, Protege, directed by Derek Yee Tung-shing, in Kowloon Bay earlier this week, the actor was toting a digital camera and took numerous photographs. He told the Chinese press he was collecting material to put on his blog ( www.kootinlok.com/blog/ ). The blog features musings on his childhood, his adult years, his work and various goings-on in his life. Koo said the blog was a channel for him to interact with his fans and also an online diary. The actor thought his writing skills passed muster, and said he was considering compiling some of the best pieces from his blog into a book.
