The first kiss ever shown in a movie was in 1896.The movie, was called The Kiss. Before and after that, kissing has been the highlight of many movies ending.   Here are some famous kisses to on film

The longest movie kiss in cinema was in Notorious 1946 between Ingrid Bergman & Cary Grant. The couple had to keep breaking the kiss up to get around the censors.

 The censorship committee decreed that no screen kiss could last longer than 3 seconds. So Hitchcock made sure that their lips never touched for longer than 3 seconds (if you put a stopwatch to it) you would find that the kiss is never over the time limit as they pull back, nuzzle, speak against each other's mouths, kiss again for 3 seconds and repeat the whole thing. It's amazing!

Very sexy! Almost neurotic! You can just tell that despite their desire for one another they are  not so trusting of each other.

CASABLANCA 1942

Rick Last night we said a great many things. You said I was to do the thinking for both of us. Well, I've done a lot of it since then, and it all adds up to one thing: you're getting on that plane with Victor where you belong. 
Ilsa But, Richard, no, I... I... 
Rick Now, you've got to listen to me! You have any idea what you'd have to look forward to if you stayed here? Nine chances out of ten, we'd both wind up in a concentration camp. Isn't that true, Louie? 
Renault I'm afraid Major Strasser would insist. 
Ilsa You're saying this only to make me go. 
Rick I'm saying it because it's true. Inside of us, we both know you belong with Victor. You're part of his work, the thing that keeps him going. If that plane leaves the ground and you're not with him, you'll regret it. 
Ilsa No. 
Rick Maybe not today. Maybe not tomorrow, but soon and for the rest of your life. 
Ilsa But what about us? 
Rick We'll always have Paris. We didn't have...we'd lost it until you came to Casablanca. We got it back last night. 
Ilsa  I said I would never leave you 
Rick And you never will. But I've got a job to do. Where I'm going, you can't follow. What I've got to do, you can't be any part of. Ilsa, I'm no good at being noble, but it doesn't take much to see that the problems of three little people don't amount to a hill of beans in this crazy world. Someday you'll understand that. Now, now, here's looking at you kid. 

Gone With The Wind 1939

Rhett I'm going to Charleston, back where I belong.
Scarlet Please, please take me with you.
Rhett No, I'm through with everything here. I want peace. I want to see if somewhere there isn't something left in life of charm and grace. Do you know what I'm talking about?
Scarlet No. I only know that I love you.
Rhett That's your misfortune.
Scarlet Rhett, if you go, where shall I go? What shall I do?" 
Rhett Frankly, my dear, I don't give a damn!
