Sky (2015)

Sky (2015) takes a French couple on holiday in the U.S. and then rips them apart, thanks to a malicious husband and an emotionally damaged wife. Diane Kruger plays Romy, the wife in question, who escapes from her husband after a bout of particularly bad misconduct on his part. She peels off in the middle of the night, concerned that she killed him in the midst of their fight, and eventually turns herself in to the police. It turns out her husband is alive and not pressing charges (woohoo!) so Romy takes off in the West, eventually canoodling with a park ranger in California. It gets messy, needless to say, and we even get a cameo from a toothless Lena Dunham. We only see Diane topless once, but we get plenty of looks at her in nothing but her underwear!
