I have no clue as to the identity of the couple being married, but Sam Waterston makes an informal appearance in their wedding video. If I could venture a guess, based on his very informal attire, he may have literally stumbled on the event. (Anyone recognize the location? I can't identify the lighthouse.) Either way, I am sure that Sam addicts will get a kick out of it. He appears at about 1:50 and then again at about 2:00.
