It wasn't a movie, but years ago (maybe 15-20) a TV Soap Opera had an Orthodox Wedding. It was a one hour show and, typically, they cut away to several scenes with other characters here and there, but the wedding itself seemed to be played out 'in real time'. If I recall correctly, it followed the Antiochian English edition. I recall that at the end, a little girl looked at her mother and asked, "Mommy, are they really married now?" and her mother smiled and said, "Yes, they are really married!" It was quite charmingly done.
