Being a blonde bombshell is very much Sydney Sweeney's vibe, so you'd be forgiven for not recognising her after this major on-set brunette hair transformation.

BTS shots just hit the internet of her filming for her new movie Eden, in Australia, and it being down under makes a lot of sense because honestly, it's like Sydney in reverse.

Her sunny blonde hair and signature look is replaced with a simple and modest brown, curled style and set into a low bun for the period movie. Meanwhile, there doesn't appear to be a scrap of make-up on her face (though given it's a film there probably is). And her pale blue polka dot dress buttoned to the collar and falling past the knee is definitely not to be found in Cassie's Euphoria wardrobe that's for sure.

We know acting is about transforming into someone else, but considering there are no special effects make-up or CGI here, it's quite wild how much she looks like a different person for her character in Eden.

Described as a 'survival thriller' about explorers in the Galapagos islands, the film also stars Vanessa Kirby, Jude Law, Ana De Armas and Daniel Bruhl. Intrepid Explorer isn't typically my genre of choice but sign me up for this one...
