Kidman appeared on the New Orleans set this week with shockingly bright blonde hair (perhaps a wig?), a big change from her recent reddish hue. The actress vamped up the look on Wednesday with lots of makeup, wearing a half-buttoned blouse, tiny denim shorts and sky-high heels.
Efron, normally a brunet, appears to have added some subtle golden highlights to his flowing hair, giving him a sun-kissed look that matches his rugged tan.
The thriller, out next year, also costars Matthew McConaughey — but not to worry, his honey-brown curls appear untouched.
