Bigfella- I don't know the tone and exact content of your documentary but publicity in a national tabloid is a great opportunity. If you pick a few up you will find that more and more of the content are just regurgitated from press releases and are not stitch ups.
Although the PR company should be telling you this anyway, write the papers a press release with snappy witty quotes and a great photo and you won't even have to speak any misquoting journalists.
Chipolata makes really good points about tabloids liking their narratives and feeding lazy stereotypes. Because of that however they like their man bites dog stories and fatman running marathon is like blonde gets degree, boy from council estates does ballet etc.
