Okay, if you haven't seen Christopher Nolan's Inception yet, consider it on your to-do list for the weekend. I'm doing you a favor here. Not only is it an incredible film, but with the recent heat (and expected rainy weekend) and a run time of 148 minutes, it's a great air-conditioned way to spend a boiling afternoon.
So, maybe psychological thrillers don't entirely make you think of weddings right off the bat, but let me just say that Inception is packed with bold colors, seasonal landscapes, and an insane variety of architecture and design. Go check it out, and maybe you'll come up with some inspiration of your own!
