I just remember only starting scene of the movie that I watched when I was a child.
There was an very formal meeting in a hotel. There was a judge and two strangers and many other guests. The couple were complete strangers. They woke up in the same bed and immediately began to discuss but they found out that the judge who loved the couple much signed their marriage certificate in the party. The next scene had two old lady workers who were joking about common first day discussions of newly wed people.
The wedding ceremony was not at the start of the film, but afterwards the complete stranger man and woman get used to each other and AFAIR they did not divorce and became happily married.
I think the movie was between 50s – 80s, a certain hollywood movie. I remember it as colored but not sure later colorized or original.
I know there are many movies that has the same plot but I am quite sure it was not What Happens in Vegas but I think What Happens in Vegas intro was inspired by this movie.
Thanks beforehand.
