Sex and the Single Girl (1964) starring Natalie Wood, Tony Curtis, Henry Fonda, Lauren Bacall and Mel Ferrer.
Not the best, but not miserable. Enjoyable mostly because I love Natalie Wood, Tony Curtis and Lauren Bacall so much.
If you watch this, watch Down with Love after. Down with Love is inspired by a lot of the Doris Day / Rock Hudson movies (as far as filming / editing style), but plot-wise? It's mostly all Sex and the Single Girl. There's also a bit of Cruel-Intentions-and-Les-Liaisons-Dangereuses-ness to it.
Sidenote (re: Down with Love) - David Hyde Pierce should be in more things. More things you can see without going to New York to see a show.
Wonderful, wonderful coat.
