Okay, this is a few days old, but I quite enjoyed this story about how talks between DreamWorks and Mandrake Pictures to remake OLDBOY have broken down. It is an interesting article, helping to point out the many problems aside from creative that potentially stand in the way of any project -- ownership and other rights, speed of development, executives changing jobs, etc.
As you probably know, there have been stories floating around about how DreamWorks wanted to remake Park Chan-wook's iconic film, with Steven Spielberg directing and Will Smith starring. But looks like all that is now kaput.
Of course, OLDBOY was loosely based on a Japanese manga of the same name, so just who would be remaking what was always a tricky question. Like the proposed remake of THE GOOD, THE BAD, THE WEIRD... just who "owns" the idea? Anyhow, all moot now.
