It's almost Halloween! And everyone knows the stars love to play dress-up.

Ben Affleck, if our calculations are correct, looks like a potential Oscar winner this year, and Denzel Washington seems content with being a very dapper barber. See those, plus Javier Bardem, Britney Spears, and a gang of wallflowers in this month's best entertainment photography.
