Katy and I went see Confetti last night (http://www.imdb.com/title/tt0427089/)
Most excellent movie. A wedding magazine is holding a “most original themed wedding” contest with 3 couples getting married on the same day at the same venue. One is a tennis-themed wedding, one is a naturist wedding and one is a big production singing/dancing wedding.
The whole thing was completely unscripted and they just improvised around the basic concept. It was brilliant. The actors didnt know about what everybody else was up to and were even encouraged not to talk to some of the other actors before filming so it would really be the first time that they met them once the camera started rolling, to keep it more spontaneous.
And the gay wedding planners were just too cute :)
