Hi Aussie Dancer,
There was a movie, "Strictly Ballroom" some years ago from down under. What was the long term effect of that movie drawing people to the ballroom dancing?
"Shall We Dance" has just came out to the movie theatre, so the effect won't be immediately know.
You mentioned the TV show "Dancing with the Stars" which is proving very popular and getting a lot of people more interested in ballroom dancing over there. That's good that TV is giving ballroom dancing the much needed exposure... It is like the Poker rooms across U.S. were once a dying breed, have became ever so popular now a days since TV aired the world series poker games on ESPN.
I hope the TV media will produce something like "Dancing with the Stars" here in the U.S.
