Way back in the good ole days when I started Raindance ('92 to be precise) we screened on 35mm, bought expensive ads in Timeout and printed and mailed thousands of leaflets.
We don't do any of that now. It's all changed, and many of the changes have happened very rapidly.
The biggest and most profound changes include
- the UK tax structures - currently the most beneficial to film producers anywhere
- transmedia and cross media storytelling
- changes to the internet
I wrote this out in quite a detailed article on the Raindance website. You can read 7 Key Trends Filmmakers and Screenwriters Embrace here
