ET caught up with A Cure for Wellness
star Mia Goth in New York City on Monday, where the actress praised her husband, Shia LaBeouf
"He's definitely one of the most brilliant actors, for sure," Goth told ET's Carly Steel. "I'm incredibly proud of him, and I have great respect for him."
The 23-year-old actress admitted that she likes to keep her private life private, and didn't reveal if she employed any of LaBeouf's help in preparing for her latest film, but she did give us her initial reaction after reading the script.
"I had to read it a good few times to really wrap my head around everything it was dealing with," she recalled. "And I think it's the same for audiences. I think it's a film you have to watch a couple times to really pick up the details and nuances of the movie."
In the upcoming psychological thriller, an ambitious young executive finds himself in over his head when he is sent to retrieve his company's CEO from a mysterious "wellness center" in the Swiss Alps. After unraveling the organization's terrifying secrets, his sanity is tested when he gets diagnosed with the same curious illness keeping all the guests longing for the cure.
The OA actor Jason Isaacs also stars in the movie.
"I had a lot of fun working with him," Goth said of the British star. "I'm just starting out. I'm quite new to all of this, and he's been doing this for a little longer, so I definitely learned a lot from him, which is nice.”
