Greta Lee and Wagner Moura channel their inner survivalists ?to play a married couple trapped inside their home in ¡°The Last House,¡± a new psychological thriller on Netflix.

Lee, who starred in the critically acclaimed ¡°Past Lives,¡± says portraying her character¡¯s emotional breakdown and how it affects the bonds between spouses, parents and children, ?was among the biggest challenges she encountered during filming.

¡°We were lucky ?enough to ?work with an actual survivalist,¡± she says. ¡°It¡¯s incredibly inspiring ?to understand the real physiology of what happens to you.¡±

Directed by ¡°Now You See Me¡± and ¡°Fast X¡± filmmaker Louis Leterrier, the movie follows a ?family of four suddenly trapped inside their house with no way out. They must ?work together as supplies dwindle and a mysterious external threat keeps them confined.

The production was shot entirely inside a single ?house that deteriorates over time, ?mirroring the characters¡¯ unraveling. ¡°The Secret Agent¡± star Moura says the set was an engineering feat: ¡°For the second part ?of the film, ?the way they managed to transform the house ?into sort of like an aquarium ¡­ I had never seen anything ?like ?that before.¡±

Leterrier, who says he has worked on movies with budgets of $400 million, admitted this was the most difficult film of his career.

¡°I¡¯ve done movies where literally I was jumping from a plane ?to another plane,¡± he says. ¡°(The Last House) was so, so difficult for everyone involved.¡±

Beyond the suspense, Leterrier says he wanted audiences to reflect on themes of consumerism and greed.

¡°I like that people will be experiencing this movie ?at ?home ¡­ and then looking at their fridge ¡­ at their family, and be ?like, how long would we survive if this happened now?¡± he says, adding ?that he and screenwriter Matthew Robinson drew on lessons from lockdown about how to ¡°survive mentally, emotionally, and grow with your family.¡±

Asked how he would fare if he were trapped at home, ?Moura jokes, ¡°That would be a disaster, really ¡ª I cannot fix anything.¡±

Lee seemed to agree, quipping that the ¡°Narcos¡± star would be best off sticking to his day job.
