Megan Fox + Josh Duhamel. I would just replace my portfolio with photos from just this wedding. I would pay for rain, give them umbrella and take a backlit picture like Tony!
I would like to photograph Tom Cruise's Scientological wedding to John Travolta because I'm pretty sure I would break the world economy (again!) with the money I'd make selling the photos to People magazine.
I'd pick Brad and Angie, and not just because they are beautiful.
I love shooting people who know how to have fun, and have tons of cute kids around to capture shots of. And I'd imagine they would put a lot of thought into an interesting, imaginative venue and ceremony. Perhaps mixing up some of the traditions of the many cultures colliding within their family.
And I've seen the photos Brad took of Angie when the twins were newborn, and he knows a good photo himself, and I like people who really appreciate a good photo.
That said, no way I'm in their league, but I can dream...
I don't keep up on hollywood couples, but a couple brides who I would love to shoot their weddings would be:
Kate Beckinsale
Audrey Hepburn
Milla Jokovich (spell check there?)
Carrie Anne Moss
Grooms?
Vinnie Jones
Mike Ski (musician)
Jason Statham
Mike Rowe (FTW)
