Back in the MSNBC days I wrote a piece on the Hollywood kiss, and included classic kissing scenes split into various categories: the desperate kiss (lovers kept apart, then not), the kiss in the rain, the manhandle, the woman takes charge, the wow kiss (the kiss that changes the trajectory of the story). 

If I were writing it today I would include this one from George Stevens' “The More the Merrier” starring Joel McCrea and Jean Arthur. It's a combination of wow kiss (Connie changes her mind about Joe) and a manhandle kiss (that takes its sweet time):

My path to the movie: Mark Harris' book, “Five Came Back: A Story of Hollywood and the Second World War” —> which led to the documentary “George Stevens: A Filmmaker's Journey” by George Stevens, Jr. —> which included the above scene from “The More the Merrier” —> which I rented from Netflix. 

Watch it with someone you can't keep your hands off of. 

Publicists had trouble coming up with a good poster for “The More the Merrier,” a romantic comedy set during D.C. in wartime, when the girl-guy ratio was 8 to 1. It was director George Stevens' last film before he went to war and filmed the liberation of both Paris and Dachau; he never made a light romantic comedy again.
