I thought you might be interested in seeing this little clip about the making of the Sony Bravia advert(see previous post). When I first saw this commercial, like some of you, I thought that many of the balls must have been produced using CGI but apparently they are ALL real. The makers thought it was important to use real balls and not 'cheat' so they basically bought up as much of the stock as they could in the US and ended up letting 250,000 of these colourful balls bounce through San Francisco!
The footage on the clip below is quite informative (just ignore the marketing bit at the front - I'm not trying to work for Sony!!). They used 23 camera men instead of the usual 4 in order to capture the live action as it happened from different angles and locations on the road. It seems you don't get too many chances to capture hurling that many balls down a hill at once. It's quite funny as it shows the crew cowering behind riot shields as they are bombarded with bouncing balls. I love seeing behind the scenes stuff. It always reminds me of my time working behind the scenes in theatre.
