Going for a Walk About

I discovered this randomly on the Internet - looking forward to seeing the film and I just started the book.  This movie seems timely to me since the actual event took place in 1977 - before all of the technology that surrounds our daily life.  What would this have looked like today?  I am guessing she would have GoPros strapped to all the animals heads, Instagram videos galore, and live Tweeting.  How far will you have to walk before you can find yourself?  I love the song that used for the movie trailer - see the posting below.
