From Variety:

OLIVER STONE TO DIRECT 'BUSH' PROJECT

Oliver Stone has set his sights on his next directing project, "Bush,"
a film focusing on the life and presidency of George W. Bush, and
attached Josh Brolin to play the title role. The director has begun quietly
shopping a script by his "Wall Street" co-writer Stanley Weiser.

Though this will be certainly be interesting (and I guess I kinda see the Bush/Brolin resemblance), I question the timing (his presidency isn't even over?) and the director (Alexander?).
