No One Will Save You is a sci-fi psychological thriller starring Emmy and Golden Globe-nominated actress, Kaitlyn Dever.

Written and directed by Brian Duffield (Underwater, Love and Monsters), No One Will Save You is described as a "captivating" and "action-packed" thriller told through the eyes of a lonely young woman with a painful backstory that's now available to stream on to Hulu and Disney Plus

The film revolves around one young woman who finds solace isolated from the rest of her local community in the house she grew up in. But one night, she finds herself roused by the sound of some so-called unearthly intruders. How will she fare against these alien invaders? 

Of the movie, Duffield said: "I wanted the movie to take the lead of a small intimate character study with a painful backstory. The end of the world won't only be for those that are ready for it, and the idea of an alien movie rudely bursting the bubble our character has spent years building and cultivating felt like a unique way to tell a favourite story."

Here's what you need to know about No One Will Save You.

No One Will Save You: first reactions

Early reactions to No One Will Save You were very positive! As of our most recent update, the film had a coveted 100% rating on Rotten Tomatoes from its first critics

The Hollywood Reporter's review called No One Will Save You a 'singularly intense experience' and said Dever 'handles the extreme emotional and physical demands of her role in powerhouse fashion', making her performance 'a virtuoso turn'.

Digital Spy rated No One Will Save You 4/5 stars, calling it both 'one of the best surprises of the year' and 'something that you'll want to experience again and again'.

IGN, meanwhile, rated it 6/10. Whilst they still heaped praise on Dever's performance, they argued the film paid too much homage to other alien invasion movies like Invasion of the Body Snatchers, Signs or Close Encounter of the Third Kind.

No One Will Save You plot

The synopsis for No One Will Save You reads: "No One Will Save You introduces Brynn Adams (Dever), a creative and talented young woman who’s been alienated from her community. Lonely but ever hopeful, Brynn finds solace within the walls of the home where she grew up—until she’s awakened one night by strange noises from decidedly unearthly intruders. 

"What follows is an action-packed face-off between Brynn and a host of extraterrestrial beings who threaten her future while forcing her to deal with her past."

Lead star Kaitlyn Dever plays Brynn Adams, the "creative and talented young woman" who will be thrown into conflict with some otherworldly beings. Her character has been described as 'a formidable fighter when it comes to her unwelcome and unearthly intruders."

Kaitlyn Dever is likely best known for starring in Olivia Wilde's raucous American high school comedy, Booksmart, and for her roles in Dopesick and Unbelievable, both of which earned her Golden Globe nominations. 

Dever has also featured in Last Man Standing, the movie adaptation of Dear Evan Hansen, Rosaline, and Ticket to Paradise. 

Brian Duffield was very happy to be working with Dever on the movie. He said: "We were so excited to have Kaitlyn join us because — like Brynn being thrust into a whole new world — Kaitlyn had never done a movie so aggressively physical and sci-fi before. 

"I think audiences will be blown away by how commanding Kaitlyn is on screen as she uses her solitude and silence to create a truly unique and complex character", he added.

Is there a No One Will Save You trailer?

The No One Will Save You trailer arrived on August 5. In it, we see Brynn heading to bed for the night, before waking up to the noise of someone breaking into her home, whilst the trailer claims that, even though there are over 1.65 million home invasions every year, this one is different. Soon, she finds herself under attack from some horrifying alien creature, and we get a few glimpses at a very different outside world. Check it out below:
