If "The Mountain Between Us" was a tale of survival of the most attractive, Kate Winslet and Idris Elba would definitely live.

Instead, as the first trailer shows, these two gorgeous strangers are stranded in the mountains and must depend on each other to survive. He's a surgeon trying to get to an emergency operation, while she's a journalist whose wedding is the next day. When their flights are delayed, she suggests they take a charter plane together.

But their plane goes down, she's injured, and there was no flight plan (so little hope of rescue). They must battle brutal conditions to find their way back to civilization.The pairing of Winslet and Elba looks promising, and they definitely exhibit chemistry in the trailer, which is good since the movie rests almost entirely on their shoulders (plus a cute dog).

"The Mountain Between Us" opens in theaters October 20.
