Rachel McAdams usually has okay, if not great hair. But this wig. . . it's bad. It's Halle Berry "Storm" bad. When will Hollywood wigmasters realize that a shellacked wigline and part just looks creepy? And platinum is fug in color, and only looks good in black and white?
And as talented as Ms. Adams is, she doesn't have showstopping bone structure - fantastic hair is key. Bad hair makes her look ugly.
