1968 sexy Italian movie
Plot: A widow discovers that her late husband had an apartment rented solely for extracurricular shenanigans and decides to use it to explore her own sexuality.
I'm now a big fan of Catherine Spaak and her versatile hair. She's really good here though there's not nearly as much nudity as you'd expect from this. Or maybe from these other posters:
This has nothing to do with the Johnny Depp movie, by the way.
