It's funny you mention Bollywood... everywhere we went, complete (Indian) strangers would say to me "hey he's handsome, he looks like he should be in Bollywood, yeah??" and I would laugh my ass off while he would stand there perplexed, not having any clue what they're talking about. It's a bit of a proud moment I guess.
Yes, Indian weddings are a big affair, with the groom typically arriving during the "barat" on a white horse. They usually last about 3 days including the mehndi (henna) ceremony, sangeet (night of dancing and singing), then sometimes up to two different wedding ceremonies and then the party when the bride arrives at her husbands' family's home afterwards.
However, ours will be considerably more low-key. I'm hoping my friend's dad, who is a former Chief Justice of the Washington State Supreme Court, will perform the wedding itself-- he's a lovely man who adores India and has an amazing sense of the absurd that would compliment us perfectly. (Sounds strange for someone serving on the state supreme court but there you go.)
Also, since most of his friends and family will not be able to attend-- US tourist visas take a while to get and we HAVE to be married within 3 months of his arrival here-- we probably won't be observing most of those traditions. It's possible we'll end up having something like that back in India eventually though, whenever that happens...
