If you want to get it seen locally you will need to help make it happen. An attempt was made to get it shown at the Edinburgh Festival, but it didn't succeed.
There are plenty of small arthouse cinemas where you can rent a screen, find one, find out how much it costs, take responsibility for organising it and crowdfund for it.
I have asked my local cinema, I am not really sure I have time to organise something like this, along with working and the other vaping advocacy stuff I do, but it isn't going to happen unless we make it happen.
The film was good, not much of it was news to me, but it would be to a lot of people. The 'Winston Man' was really interesting and probably the star of the show.
