Whether you're checking into a nearby spa for the day or heading further afield for a lengthier stint of bliss, visiting a wellness retreat is supposed to be relaxing. But that doesn't seem to be the case in upcoming miniseries Nine Perfect Strangers. The star-studded show was shot in Byron Bay, so it looks the scenic part — but the nine guests who turn up in search of a new lease on life all appear set to get much more than they've bargained for. That's how the series' new trailer unfolds, at least, with the latest sneak peek offering a bigger glimpse at the show following a very brief clip back in April. Given the cast involved — including Nicole Kidman (The Undoing), Melissa McCarthy (Thunder Force), Michael Shannon (Knives Out), Luke Evans (Crisis) and Asher Keddie (Rams) — Nine Perfect Strangers is easily one of the big series of the year, and that long list of famous faces will be navigating quite the eerie and creepy situation. Also part of the show: Bobby Cannavale (Superintelligence), Regina Hall (Little), Samara Weaving (Bill & Ted Face the Music), Melvin Gregg (The United States vs Billie Holiday), Asher Keddie (Rams), Grace Van Patten (Under the Silver Lake), Tiffany Boone (The Midnight Sky) and Manny Jacinto (The Good Place), who'll all navigate a ten-day retreat overseen by Kidman's Masha throughout the drama's eight episodes. The latter oversees a resort that promises to transform nine stressed city-dwellers — but, clearly, things aren't going to turn out as planned for the show's titular figures. As with Kidman's last two miniseries — Big Little Lies, which like Nine Perfect Strangers, was also based on a book by Liane Moriarty; and The Undoing — David E Kelley (LA Law, Ally McBeal, Mr Mercedes) is leading the charge behind the scenes. He's the show's co-writer and co-showrunner, with Long Shot's Jonathan Levine directing every episode. And if you're wondering where and when you'll be able to see the results, Nine Perfect Strangers will stream Down Under via Amazon Prime Video, with the series set to debut on Friday, August 20. Check out the full trailer below: Nine Perfect Strangers will start streaming in Australia and New Zealand on Friday, August 20 via Amazon Prime Video — starting with its first three episodes, with new episodes then dropping weekly afterwards.
