You'd think the only thing Josh Brolin would have had to study to play George W. Bush in Oliver Stone's W earlier this year would be video and audio of the president.
Not so.
Brolin also took a good look at rodents for inspiration to play George W. in his younger years.
"I would watch rats in mazes looking for cheese because that how I saw him looking for women," Brolin tells James Lipton on Inside the Actor's Studio, airing Jan. 5. "He always leaded with his head."
Also revealed in the interview, Brolin tells how he snagged the role of another real-life politician, murderous San Francisco city supervisor Dan White, opposite Sean Penn in Milk.
