I went to a friend's wedding, and while they didn't do the costumes, all the music, including the march was from Star Wars, and there were huge ice sculptures, one in the shape of Darth Vader and one in the shape of Leia.
I was always a little suspicious of them after that, hehe.
Yeah, I guess I don't see the difference between "Wedding as a carefully planned and costumed theater based on traditional but archaic conventions" and "wedding as a carefully planned and costumed theater based on Geeky Hobby Of My Choice."
That looks like fun. I've been to lots of weddings over the years and the only ones that I really remember are the cheap and cheerful, not quite normal ones. The ones that cost a lot and had the big church and the big hall just blur into one.
