Columbia Pictures is close to securing a director for its Facebook movie: David Fincher, of Fight Club fame, is reportedly in advanced talks. He'll be expected to move fast, before the market for a movie about the social network evaporates.

Columbia wants to start production by the end of the year, according to Variety, even though the book on which the film is based won't be released until July 14. So even assuming screenwriter Aaron Sorkin is working on advance manuscripts, he and his colleagues will need to move quickly.

The book is being done by admitted fabricator Ben Mezrich, so they should probably start with the fact-checking.
