Chiwetel Ejiofor & Chris Pine in Z for Zachariah (2015)

Z for Zachariah is a drama based on the novel by Robert C. O'Brien. It tells the story of Ann, a woman who has survived in the wake of a disaster that has wiped out most of civilization. When she discovers another survivor, John Loomis (played by Chiwetel Ejiofor), the two begin to bond until the arrival of another man (played by Chris Pine) causes major sexual tension. Chiwetel strips down to wash off in the water and later gets a scene with some glimpses of side nudity as he's washed off after bathing in the contaminated water. Chris gets a shirtless scene as well when he answers his bedroom door wearing only a towel, leading to a sexual encounter with Ann.
