The actress has undergone an extreme image overhaul for her new movie, but is it a case of hair today, gone tomorrow?
Sandra Bullock is no stranger to a movie makeover - remember her blonde moment for The Blind Side? - and she's done it again, sporting a lighter, curly 'do while filming new flick, Extremely Loud and Incredibly Close in New York.
But is it a case of hair today, gone tomorrow?
It is unclear whether Sandy has hit the dye bottle or is simply wearing a wig for the role - the new look certainly pales in comparison to her signature glossy dark mane.
The Oscar-winning actress is busy shooting the movie alongside Tom Hanks, which is based on Jonathan Safran Foer's acclaimed novel. It marks her return to work after an 18-month hiatus, in which she adopted her son Louis and divorced husband Jesse James.
Whether it's a wig or not, we still want your opinion on Sandra's latest look: should she stick to the dark side, or do you like her lighter tresses? Let us know your verdicts in the comments box below....
