Sydney Sweeney looks unrecognisable with brunette hair while filming the upcoming survival thriller Eden in Australia

Sydney Sweeney has said goodbye to her blonde locks to film the upcoming survival thriller Eden in Queensland, Australia.

On Monday, the Euphoria actress, 26, looked unrecognizable with her new brunette locks as she filmed with her co-star Daniel Brühl on the Gold Coast.

The beauty sported a darker hair color when she stepped into her role for the project – which is being directed by Ron Howard.

She also wore an olive-colored ensemble that consisted of a belted jacket and shorts.

The star also donned a pair of knee-high socks and brown boots to complete the look.

Her hair was parted to the side and styled in a chic chignon for the busy filming day.

Sydney was seen strapping two wooden boxes onto an easel during the scenes, and in between, an assistant held a blue umbrella to help block out the bright sun.

She also had her hair fixed and adjusted before stepping back in front of the camera.

The White Lotus star was joined by Brühl to film a scene with the animal, and The Alienist wore a similar ensemble to Sweeney.

Daniel has worked with Howard in the past, including on the 2013 film Rush.

The filmmaker has worked on several films in the past, including A Beautiful Mind (2001), How The Grinch Stole Christmas (2000), The Da Vinci Code (2006) and most recently Thirteen Lives (2022).

In addition to Sydney and Daniel, the star-studded cast also includes Jude Law, Ana de Armas and Vanessa Kirby.

The premise “follows a group of people fueled by a deep desire for change; To turn their backs on society, they leave everything behind and focus their future on the harsh landscape of the Galapagos,” said IMDB summary.

Producers of the thriller – which also includes Howard – told Deadline last October that the film “explores the human condition in ways that are unexpected, absurd, humorous, sexy, but above all exciting and deeply suspenseful.”

Both Sweeney and Kirby replaced actresses Daisy Edgar-Jones and Alicia Vikander who were initially cast in the project.

Noah Pink wrote the screenplay for Eden – which was originally titled: Origin Of Species.

According to Deadline, Hans Zimmer will score the film and this will be the composer’s tenth time working with Ron Howard.

During an interview with Business news Australia earlier this month Ron expressed his excitement to return to Queensland, where he also filmed Thirteen Lives.

“I have always been impressed by the professionalism and creative spirit of the Australian film community,” said the filmmaker.

“My experience with our Queensland crew on Thirteen Lives only confirmed that and more,” he added. “I am thrilled for the opportunity to bring Eden to Queensland and continue the partnership.”

Last week, an Australian man’s fantasy came true when he received a private message from Euphoria star Sydney.

The blonde beauty messaged TikTok user Mileshep after he posted a video of seeing the American actress on a Gold Coast beach as she emerged from the surf.

After the video went viral, Sweeney wrote to him, “You should have said hi.”

Mileshep shared a screenshot of the message with his followers and then asked the White Lotus star out on a date.

“Ahaha yeah, how about if I take you out and I can say hi for real x,” he said in his response.

Unfortunately he did not receive a response.

In his original TikTok video about his sighting of Sydney, Mileshep said he was “still processing” the experience, likening the encounter to meeting a “Bond girl” or supermodel.

“Sydney Sweeney, also a real standout in her prime,” he said.

“…My eyes were blessed with something I will never forget: that image is locked up here forever,” he said, pointing to his head.
