Sydney Sweeney unveiled quite a dramatic make-under for her role as the real-life German settler Margret Wittmer in the first trailer for Ron Howard’s $50M-budget survival thriller Eden, which debuted Wednesday.

Audiences are used to seeing the 27-year-old Euphoria stunner looking every bit the Hollywood blonde bombshell.

Sydney’s character was four months pregnant when she moved the Galápagos archipelago’s Southern most island Floreana in 1932 with her husband Heinz (Daniel Brühl) and stepson Harry (Jonathan Tittel).

Sweeney reportedly has a wild birth scene in Eden where she fends off feral animals just as her water breaks, and Margret eventually welcomes a son and daughter on the remote South American isle.

The tight-knit community soon discover ‘their greatest threat isn’t the brutal climate or deadly wildlife, but each other’ as Eloise Bosquet de Wagner Wehrhorn (Ana de Armas) and Dr. Friedrich Ritter (Jude Law) begin wielding guns.

‘Trust me by this time next year, one of us will be gone,’ Eloise warned Friedrich. ‘I personally hope it’s not you.’

The Cuban 37-year-old’s wealthy ‘baroness’ character is also seen engaging in a wet and wild threesome with her two devoted male companions in the ocean.

In one ominous shot, a mystery person is seen throwing another person off a massive seaside cliff.

‘They’re trying their best to ruin us,’ Margret told Heinz. ‘They won’t, because we are a family.’

The real Margret Wittmer was buried on Floreana Island in 2000 when she died, at age 95, after expanding the settlement and writing about her experiences in the 1959 book Floreana: A Woman’s Pilgrimage to the Galápagos.

The Echo Valley actress replaced Daisy Edgar-Jones in the role back in 2023 due to her commitment to Twisters amid the SAG-AFTRA strikes.

German-born Diane Kruger previously voiced Margret in Daniel Geller and Dayna Goldfine’s 2013 documentary The Galapagos Affair: Satan Came to Eden.

‘It’s every actor’s dream to work with Ron. I grew up loving your films, but being able to work with you, I have just learned what an amazing human being you are,’ Sydney gushed during the Q&A at the TIFF premiere on September 7.

‘And when Margret came to me, I was absolutely amazed by [it being] a true story and it wasn’t her choice. And she had to follow her husband’s footsteps and she had no idea what she was getting herself into. She was a child at that!

‘And it was just such a crazy character journey for her and for all the other characters. And I absolutely wanted to dive into it. And with such an amazing cast, I mean, this is like a dream to be able to be a part of, but I’m just really lucky.’

Thus far, Eden has earned a dismal 57% critic approval rating (out of 30 reviews) on Rotten Tomatoes.

The movie formerly known as Origin of Species – hitting US theaters August 22 – also stars Vanessa Kirby, Felix Kammerer, Toby Wallace, and Richard Roxburgh.

But first, audiences can catch Sweeney as South Dakota waitress Penny Jo Poplin in Tony Tost’s modern-day western Americana, which finally hits US theaters August 15.

Lionsgate’s long-delayed crime thriller – formerly known as National Anthem – also stars Halsey, Paul Walter Hauser, Eric Dane, and Simon Rex.

The Spokane-born, LA-raised beauty recently reprised her breakout role as Cassie Howard in the eight-episode third season of HBO hit show Euphoria, which is produced by and starring Zendaya as Ruby ‘Rue’ Bennett.

Sam Levinson’s drug-fueled drama will welcome newcomers Sharon Stone, Rosalía, Marshawn Lynch, and Kadeem Hardison in season three.

In January, Sydney was hard at work executive producing and starring in Paul Feig’s big-screen adaptation of Freida McFadden’s 2022 novel The Housemaid, which Lionsgate plans to release in time for Christmas.

On November 25, Sweeney wrapped her role as professional boxer Christy Martin in David Michôd’s untitled biopic, which she called ‘one of the most emotional, transformative experiences of my life.’

This summer, the Fifty-Fifty Films co-founder will begin producing and starring in her Euphoria castmate Colman Domingo’s feature directorial debut Scandalous! about the love affair between Kim Novak and Sammy Davis Jr. (David Jonsson).

Sydney is very much in demand with several projects in the works including the Reddit-based thriller I Pretended to Be a Missing Girl for Warner Bros, Jon M. Chu’s sci-fi flick Split Fiction for Amazon MGM Studios, and she’s producing Michael Bay’s video game adaptation OutRun for Universal.

Aside from her movie career, Sweeney is every bit the influencer with lucrative paid partnerships for brands like Samsung Mobile USA, Dr. Squatch, LANEIGE US, Bai, and HEYDUDE.
