Referring to his character in the upcoming The Book of Eli, EW says:
"Don’t be fooled by Oldman’s character’s Commissioner Gordon glasses; he’s a grade-A wackjob. On the Oldman Scale, I’d place his Eli character some place between the dreadlocked pimp in True Romance and the southern-accented space terrorist in The Fifth Element. Welcome back, bats--t crazy Gary Oldman. I missed you."
Maybe he's a grade-A wackjob on screen, but co-star Mila Kunis says Gary Oldman isn't scary to work with (from Hollywood Outbreak...listen to the short audio clip).
