Goyer, Nolan back to write 'Batman'?

David Goyer and Jonathan Nolan have reportedly started work on a script for a Dark Knight sequel.

According to Deadline Hollywood, Goyer has left his role as showrunner on FlashForward to concentrate on his movie career.

Goyer penned the script for Batman Begins and shared a writing credit with Jonathan and director Chris Nolan on its 2008 sequel.

It is unclear if helmer Nolan, whose sci-fi film Inception is due out in the summer, will return to the director's chair for a third Batman.
