It really is a very good movie, y'know. It has its soft spots--especially if you know anything about the real history of the real Trapp Family (by the time they were performing, the youngest of the kids was something like 17 years old... and where, oh where, is Franz Wasner?)
But the "travelogue" and scenery aspects really are wonderful, Julie Andrews really is a very good actor and a very good singer, the Lindsay and Crouse script is much better than the average musical... it's hard to believe Julie Andrews as a 21-year old woman (but a lot easier than believing a 46-year-old Mary Martin). It's wish-fulfillment for anyone who had an emotionally cold parent and hoped they would be magically transformed into a warm, loving parent.
I still hate the song "Do-Re-Mi." I hated it when Mary Martin and the Broadway company performed it on the Ed Sullivan Show and it hasn't improved with time. At least in the movie you can be distracted by the genuinely engaging antics of Andrews and kids touring effortlessly around Salzburg.
So, yeah, I read this book about it... good book... The Sound of Music Story [sic] (shouldn't it be The "The Sound of Music" Story?) by Tom Santopietro. Funniest detail. The IMHO convincingly-acted scene in which Georg and Maria declare their love is filmed just gorgeously in silhouette, as they stand in a gazebo with the background of a twilight-lit garden behind them. According to Santopietro, the plan had been different:
UltimatelyAndrews had passed the point of total exhaustion, and by her own admission, whenever tired, she becomes "wobbly" and starts to laugh. Her efforts not to break up resulted in her falling apart again, and Plummer soon joined her in uncontrollable fits of giggles.
McCord found it necessary to flood the set with light from oversized arc lamps.... when the carbons in those old-fashioned lamps brushed against each other, they emitted a sound remarkably similar to that of someone passing gas....
With the pressure mounting, and time/money wasting, Andrews and Plummer continued to laugh their way through through their ballad...
Wise came up with the idea of shooting the scene in silhouette: faces would be seen only in profile, and the goofy grins and chortles could skim by unnoticed.
