Whether they walk down the aisle in 2012 or 2013, there’s no doubt that Brad Pitt and Angelina Jolie will star in the wedding of the year. We asked a quintet of A-list wedding planners to unveil ideas to help the most boldface bride and groom of them all tie the knot.

PLANNER: Marcy Blum, whose celebrity wedding clients include Billy Joel, Colin Hanks, Salman Rushdie, Tom Clancy

The locale: “Some sort of magnificent structure.â€� Pitt is “such a visual person. He’s designed so many homes, and now the ring,â€� that Blum could see collaborating with him on a modern building that takes the typical tent cake “because that’s where his tastes run. … They can’t do anything outside, unfortunately, unless they can fool everyone to where it is.â€� One place Blum believes the couple has crossed off their short list because it’s at the top of everyone else’s: Their South of France chateau.

The guest list: Under 100 family and close friends.

The vibe: “Very low-key, and it should be … soft and understatedâ€� and family-oriented, with the kids playing a prominent role. “The kids will definitely, it seems to me, be very much a part of the ceremony.â€� The idea is “not to just cut to the chase and get to the party as everybody does, but have a more meaningfulâ€� service that taps into the couple’s spirituality — and the children’s reported wish for a fairy-tale affair. “They want it to be out of Shrek.â€�

The entertainment: A similarly boldface band. “A lot of friends and acquaintances are going to pitch in and perform,� doing double duty as guests and singers or players. “It’s part of the gift, almost.�

PLANNER:Colin Cowie of ColinCowieWeddings.com, whose celebrity clients include Alyssa Milano, Eddie Murphy, Holly Robinson Peete

The locale: Two venues: The first would spirit Pitt and Jolie and just their immediate family members to a luxurious South African safari camp. The second, two weeks later, would be a cocktail-style reception for friends at their house in L.A.

The vibe: For the African ceremony, warm and intimate: “I could imagine them getting married with a stunning African sunset under a large old tree hanging with dozens and dozens of lanterns.� For the L.A. party, the complete opposite: “Instead of buffets, I would have stations of food paired with great wines and cocktails,� culminating in a wedding-cake cutting to create a “fun, glamorous night.� To bridge the two events, at the end of the night, each party guest would receive a small booklet filled with “stunning images� of the family wedding abroad.

The guest list: In Africa, closest family only. In L.A., 200 friends.

The entertainment: In Africa, they would be serenaded by the local village choir. At the California reception, a musical mashup: A couple of rock violinists and a percussionist would accompany someone like DJ Cassidy, who spun at Beyonce and Jay-Z’s bash. For the cake-cutting portion, a song by the pair’s favorite artist.

PLANNER: Jung Lee of Fete, whose celebrity clients include the Bulgari family, Stephen King’s son Owen, Jann Wenner’s son Alexander

The locale: Lee believes the rumors: Chateau Miraval. “It’s a revealing of the property for their closest friends and family that haven’t had a chance to visit yet.� Besides, “you can’t rent something like that.� Regardless, this will be an event that requires passports. “For sentimental reasons, I would love for them to actually have the wedding and give the proper glamour to the States, but I think it’s probably not feasible. They’re not going to have the privacy they need.�

The guest list: 200-300 people, “for sure.�

The vibe: “I would be completely shocked if it would be an all-white sort of wedding.� So Lee envisions noir nuptials: black mirrors, 2-foot candlesticks, dark, rich flowers and, juxtaposed against the 14th-century surroundings, sleek, contemporary furniture for lounging. But it wouldn’t be all adult lair. Lee sees lots of children “running around the sprawling lawn. It can’t be more magnificent than that — sort of heaven on earth.� And for a late-night snack? Considering the clan’s photographed penchant for junk food, mini bags of McDonald’s cheeseburgers, french fries, hot apple pies and shakes flown in. It would satisfy the kids — and show the newlyweds’ sense of humor. “You’re drinking and you smell that oily McDonald’s? People live for it. People clap for it sometimes when we bring it out.�

The entertainment: “Amazing acts like U2 and Elton John— just great bands that are also among their friends.� Guests are going to “get down and dance.�

PLANNER: David Tutera, whose celebrity clients include Los Angeles Clipper Chris Paul and Shannen Doherty

The locale: A “very exoticâ€� venue that is most definitely not in the USA. “They’re so international. Think about the time they spend together as a family and as a couple. It’s not in the States. … Doing it in America sort of to me goes against who they are.â€� So think private island, “up on a mountain or in a rain forestâ€� — a “challenging destinationâ€� for paparazzi to reach.

The guest list: 100-150 friends and family. “Nobody in the business.�

The vibe: “Very Baliâ€�: copious quantities of candles; local organic food that’s indigenous to the setting; dark wood tables adorned with “lots of incredibly interesting almost artifacts,â€� such as foliage-filled bowls; earth-hued flowers in greens, oranges, khakis, coppers and champagnes. The look is “very tropical, but not kitschy tropical … pretty but not prissy, not girly-girl.â€�

The entertainment: “Someone you would sit and enjoy,� like Adele. “I don’t really see this as a dancing party.� Likewise, forget those cliched “I do�-uttering traditions. “The first dance, the throwing of the bouquet — I see them not doing that at all.�

PLANNER: Diann Valentine, whose celebrity clients include Usher and Tameka Raymond, Jennifer and Eric Williams of Basketball Wives, Martin Lawrence, Toni Braxton, Evelyn Lozada of Basketball Wives and NFL player Chad Ochocinco

The locale: Their own private island, such as the $75,000-per-night Calivigny, off the coast of Grenada. The French colonial- and Balinese-style main house boasts 10 suites outfitted in designs by Oscar de la Renta and Richard Frinier. The price tag notwithstanding, it’s a relatively casual setting fitting the Jolie-Pitts, Valentine says. “They tend not to live a very flamboyant, ostentatious lifestyle.�

The vibe: A weekend of individual activities and group breakfasts and parties, including the most important bash of them all: the wedding, but the guests — and kids — wouldn’t know when they were saying “I do� until the moment it happens. The ceremony itself? A stripped-down affair “definitely� devoid of bridesmaids, groomsmen attendants, ring bearers and wedding cake — “none of that foolishness.� The cuisine, whipped up by private chefs from different regions of the world, would pay homage to the children’s homelands, from Africa to Southeast Asia. The decor would be “very sleek, very clean�: teak furnishings, neutral fabrics, seagrass mats — no “ugly white vinyl� tents. The goal? For guests to “walk away with a greater appreciation for something bigger than the USA.�

The guest list: “Very small and intimate�: 50-75 family members and friends.

The entertainment: “A very eclectic mix of music that is not about celebrity but more so about their personal taste,� representing the same cultures their family hails from. So think African dance troupe or choir plus opera singer plus, perhaps, Coldplay.

Wondering how to choose the right venue for your wedding? Here’s what you need to know, from etiquette and planning expert Kate Chynoweth, author of “The Bridesmaid Guide: Modern Advice on Etiquette, Parties, and Being Fabulous.” Have questions? Ask in the comments.

Choosing a wedding site is about more than finding a spot with charm; it’s about meeting all the needs you have as a bride. Unfortunately, juggling those needs — which probably include your own religious considerations and those of others, your aesthetic preferences, and practical factors such as the bottom line number on your guest list — can quickly start to feel like a less-than-amusing circus act. To complicate things further, often everyone from your fiancé to your family has a strong opinion about what is most suitable.

Fortunately, the choice of venues these days is incredibly diverse. Couple can decide to pledge their vows at a rustic winery, a beachside retreat, or an ornate cathedral. Start your decision-making process by putting ideas on paper. Write down your dream locations and then make a practical list of the benefits and drawbacks each provides. Do you want a wedding with a dose of tradition? Many quaint country chapels are non-denominational and welcome couples of any religious faith — yet they may be too small for a large guest list. Is being outdoors important? Locations like wineries that are frequently used as wedding venues are beautiful and practical but often booked long in advance.

As your ideas come together, remember to be realistic about your own organizational skills. You might find a pristine beach that seems ideal for a wedding, but managing details like how the reception tent will be delivered or where guests will park can create a lot of stress. Above all, remember that while finding the right venue is partly about pleasing everyone else, it’s also about making good on your own hopes and dreams for your wedding. When striking a balance between your vision and the practical considerations feels like a challenge, just remember — your reward will come in the form of beautiful memories that you’ll always keep.
