In Brian DePalma’s Passion, Rachel McAdams is shown kissing two different girls, and in lingerie, in a bubble bath and in the shower but she never gets naked. We do see Rachel wearing a silk negligee after said shower at about 61 minutes in. There is some major pokie action as Rachel applies some cream over her body.
Passion wasn’t a total waste of time though since Noomi Rapace is shown making a sex tape roughly 11 minutes in. We get brief views of Noomi’s breasts from an over the shoulder view as she is getting it missionary style. Lastly, at 63 minutes in, we see Noomi get out of bed topless and answer the door but I don’t think you can actually see anything except her bare back.
