Old man Logan my arse. Superb story that will not be filmed, no matter how much I wish it would be.
Remember that the last Wolvie film was supposedly based on the Claremont/Miller japan story, and in actual fact was not based on it at all!
How about Civil War? Great film, but not based on the book.
So don't hold out too many hopes for a proper Old Man Logan. Hopefully it'll be good anyway...
