In the thriller genre, you can’t beat the simplicity of a survival movie – where a character, or characters, are pitched in an impossible situation of near-constant peril, forced to think quickly and act smartly with every passing minute to ensure their continued longevity. And if you enjoyed the likes of The Shallows (Blake Lively vs. a shark!), you’ll want to get excited for Horizon Line – the new film by Michael Marcimain, which takes Get Out and Girls star Allison Williams and The Last Kingdom’s Alexander Dreymon, flies them thousands of feet in the air, and leaves them to make their own landing. They play a pair of exes who find themselves in mortal peril when the pilot flying them to an idyllic island wedding on a tiny plane suddenly carks it, and they have to complete the journey themselves.
