M. Night Shyamalan has spoken about the possibility of working on one of the remaining Harry Potter films.

The Lady in the Water writer-director was forced to turn down an offer to direct the first film, and although still open to idea he sees that there are some obstacles.

He told Coming Soon: "You know, that Harry Potter dance has gone on a long time. The problem is that it is a living breathing thing now, all by itself. When it comes over to my camp, it needs to be kind of handed over, adoption papers and everything. That's a tricky move."

"I haven't met with J.K. [Rowling]. The first one was offered to me, but that conflicted with Unbreakable, which was unfortunate. I would definitely, but I think probably before that I would adapt a book. I've gotten close a few times to adapting books," he added.
