This dance sequence between William Holden and Kim Novak from Picnic
is considered one of the sexiest on film. It was choreographed by Jerome Robbins and it's one of my favorites.
Incredibly sexy. William Holden was actually pretty drunk when this was sequence was shot so Kim Novak had do the leading.
You'll see Holden first, then Novak comes into frame and the dance begins shortly after.
