Which actors or actresses fake their kiss scene?
Usually "French" kisses on screen, especially in TV or PG movies, consist of actors pressing their lips while opening and closing their mouths. With their lips sealed as they do this, what goes on inside their mouths is hidden from view. This presents the illusion that their languages meet, but in reality they are not. It's just an assumption that the audience makes.
In more explicit movies, the actors will really get tangled up in tongues. Even in those cases, however, the action of the tongue generally remains fairly moderate. This is not necessarily because the actors would feel uncomfortable; these people are generally professionals at doing things on camera that would make most mere mortals uncomfortable. Rather, passionate French kisses between two stimulated people are actually messy-looking, and not the most romantic or picturesque things to see in detail on a big screen.
Here's an example of an "explicit" Hollywood kiss (sorry, it's one of my favorites):
As complete as this kiss looks, seeing a close-up kiss between two lovers, with all the details that an HD camera would capture, would generally not look like this. For the sake of cinematography, Hollywood offers us a much friendlier fantasy about what it's like to kiss.
In their defense, I think directors and actors seek to portray how good a kiss feels to the people involved in it, rather than present a realistic version of what it might look like to a viewer, which I think is the highest priority. in most stories. .
