When it comes to musical weddings, you can't do better than Julie Andrews and Christopher Plummer as Maria and Captain Von Trapp in "The Sound of Music." The duo doesn't actually sing during the ceremony, but the scene is so beautifully shot and the event is so visually breathtaking that the stars' impressive pipes aren't missed.
Maria wears a beautiful white wedding gown with a lengthy train, and Capt. Von Trapp appears in his full dress military regalia. The two are wed in Nonnberg Abbey, the female convent of Maria's former order (though the scene was actually filmed in a church in the small Austrian town of Mondsee).
