City of Sin (2012)

Originally released in 2012 as Hotel Noir, City of Sin is a rerelease of a classic neo-noir film featuring one incredible cast. Set in 1958, a detective steals a bunch of "loot" and retreats to a swanky hotel, where he awaits a crowd of angry hitmen. While he's there, he meets a bevy of hotel guests that are somehow all interconnected - and will all ultimately help save him from peril. A bevy of A-list celebrities are in the cast, including Malin Åkerman, who shows bare back while she's in bed with a lucky guy, Mandy Moore in a cone-shaped bra when she's asking Danny Devito to ravage her, plus Carla Gugino and Cameron Richardson making out in the rain (on a tennis court). There's no full-blown nudity here, but it'll still inspire some sin of your own!
