Identity (with John Cusack) - really good

Sabotage (with Arnold Schwarzenegger) - no isolated location, but murdered 1 by 1

i can´t think of any more atm but i might remember some more later

Most such stories are deliberate imitations of “And Then There Were None” and even reflect it in their titles.

Lots of TV shows have had this sort of episode. (Often the people have been kidnapped, not killed, so that the cast is left intact). GILLIGAN'S ISLAND( actually called “And Then There Were None”), GET SMART (“Hoo Done It”) , LOST IN SPACE(“The Space Creature”), STAR TREK NEXT GENERATION(“Remember Me” ) , XENA WARRIOR PRINCESS(“Ten Little Warlords”) are the ones I've thought of right off.

===========================================

KIND HEARTS AND CORONETS, ALIEN, and HUNGER GAMES nearly fit, but they are not mysteries: you know who is doing it.

The Thing, Alien and The Hateful Eight.

Murder by Death, in which the characters are parodies of well-known literary detectives, such as Miss Marple, Hercule Poirot and Charlie Chan, and the host, Lionel Twain, is played by Truman Capote. A nice little gem of a movie, with suspense and humour.

"Don't Blink" - although it's more a sci-fi tale than a murder mystery. I love "The Last of Sheila" also - wish it would be remade by the BBC into a quality mini or at least a longish TV movie.

You might also like the 1974 film version of Christie's OTHER most famous book, Murder on The Orient Express. A similar set-up, lots of suspicious characters trapped on a luxury train that's been snowed in at a remote countryside location, but the plot is kind of the polar opposite of And Then There Were None (can't say more without spoiling it.) Lots of really, really famous people in it.

Like others have said, while not an extremely close match to ATTWN, "The Last of Sheila" is probably the best mystery film I've ever seen. It played completely fair with all the clues to unravel the mystery, and yet I missed pretty much every clue to tip me off to the ending. Plus, it has a fantastic cast of actors, including the legendary James Mason, who was my favorite character in the film, Richard Benjamin, James Coburn, Dyan Cannon, Ian McShane, Rachel Welch, and Joan Hackett.

For similar films to this, "April Fools Day" is a 1980s slasher-type film that really follows the ATTWN narrative, and one of the potential victims is played by the comic villain of "Back to the Future," Thomas F. Wilson.

"The Burning," also a 1980s slasher, follows a similar theme, though "April Fools Day" is a much closer clone to ATTWN

I also really enjoy "Five Dolls for an August Moon," It's an early Mario Bava film. It's a very generous rip of ATTWN. The characters are all wealthy, and end up stranded on Teodoro Corra's private Island. A group of wealthy industrialists are trying to buy off a formula from William Berger, and start getting bumped off one-by-one by an unseen killer. They don't let the party stop however. I suggest seeking out the english dub. I love the music, the acting is, shall we say, adequate, though no one seems too nervous about the bodies piling up. It goes a little towards black comedy, in that the victims end up getting bagged and placed in Corra's walk-in freezer for safekeeping.

It's the closest thing to ATTWN I've seen that isn't a direct remake of ATTWN. If you can handle kitschy 1970s music, it's a film for you. I stumbled upon the title while reading a review for a version of 10 little indians. Saw the non-dub but subtitled version on Nexflix and enjoyed it so much I had to own a copy for myself. It ended up making me a fan of Teodoro Corra, I dug his double-breasted blazer ensembles.
