I didn't even realize that this was already out in theaters, although in a very limited release, playing on just one screen in the entire country. It looks like it may be gone from theaters.
But don't fret, if you were interested in seeing it, because it'll be released on home video in early February. So you don't have very long to wait.
Cinedigm and New Video acquired domestic (USA) distribution rights to In Our Nature, which premiered this year at the SXSW Film Festival, earlier this year.
