In Our Nature (2012)

A scheduling conflict leads to a heart-to-heart between an estranged father and son in In Our Nature (2012). Friday Night Lights' Zach Gilford stars as Seth, who plans to propose to his girlfriend Andie (Jena Malone) while on a romantic weekend getaway at his family's cabin. But just as the two are christening the cabin with some nookie, in walks Seth's estranged father Gil (John Slattery) and his new lover Vicky (Gabrielle Union). Yikes. But what's even more mortifying is that besides a bra shot from Gabrielle 56 minutes in and a quick, now-you-see-tit-now-you-don't glimpse of Jena getting busy on the floor at the 8 minute mark, there's not much to give you wood in this log cabin.
