I am 46 years old. This movie has aired on network TV just about every year of my life, and I have yet to watch it in its entirety.
Reading this list almost makes me want to. :)
We're the same age. I could probably recite the script by heart!
When I was growing up, watching this movie was an annual tradition in my family -- because, of course, "back in the day" you could only watch network TV, when they chose to air it, and there was no such thing as "recording." At Thanksgiving it was The Sound of Music, at Easter it was Ben Hur.
I don't know if it was because my mother just liked the movie... because we were Catholics and it was "about" Catholics.... or what. But my sister and I (and my brothers, I guess, by default LOL) would mark the calendar, pop the corn and get to stay up late to see TSoM in all its glory. To this day, I love the dance scene on the terrace between Maria and Capt. VonTrapp!
