Barry Eisler has weighed in on Rain and Keanu Reeves in a post that he published on his website. In a nut shell,the project is in the early stages of development and it is not clear who will be in the cast, what network will acquire the series or what countries it will be available in. Regardless, he appears pleased that Keanu is attached to the project and thinks the action will be awesome with Chad Stahelski and David Leitch involved. Mr. Eisler also discusses the character John Rain among other things. You can read the entire post here.
