The link above leades to this poster for the mid-century travel film, "If it's Tuesday this must be Belgium", featuring a famous actress falling into a fountain in Rome. I remember watchng the movie on TV as a kid, from what I remember it was good.
I know this rather frustrating lobby card well. It is very misleading since there is no such shot actually in the movie. This often happens with movie promotions, they promote a picture of a scene that is not shown in the film that way.
In the film all you see is head shot of Suzanne falling into the fountain and then they CUT the scene right away and you never see the shot as depicted in the still photo.
There are many instances of pics in lobby cards of scenes that don't exist in the film. Not only wetlook scenes but many iconic movie promotion photos for mainstream movies too ..all the famous pics of Marilyn Monroe's skirt blowing up as she stands above the subway grate in the film "The Seven Year Itch" don't exist at all on film either....only in still photos. The upskirt scene was shot but only from the waist up because the director and censors would not allow her to show the full body scene because her underwear was so sheer the censors would not allow it on film.
