I was thinking about Heathrow dJen after your comment and how it has been used as a location in adverts and films. Have you seen "Love Actually"? That gives you some idea how the Heathrow setting is used to tug at the emotions, especially at Christmas. I must get the dvd out to watch again next month!
I've just seen the Heathrow ad and I think it's very sentimental but also patronising to elderly people portraying them as confused and anxious old teddies!
I disagree pollyperkins, most of us pre date that advert, (I was flying BOAC as a child in the 1960s to visit family across the world), so the idea of the teddies ageing over the years and their changing personalities is very true to life, just as I feel somewhat overwhelmed by the same trips now in my later years.
Not quite sure why they had to be teddies though, but I guess it's to do with Paddington bear, although thinking about it did he arrive from Peru by plane at Heathrow or did he use a different means of transport to arrive at Paddington?!?
