The UK was generally accepting of trans people (other than the occasional bigots), but in the past decade there has been a steady increase in transphobia, mainly pushed by the print media and our pathetic government. They see it as a "wedge issue" and are using it to distract from the appalling job they have done in running the country. It's working too. I have talked to people who should know better, who think they have "genuine concerns" about trans people in sports, prisons and toilets.
It's quite depressing how easily it's done really.

There was also a radio series and LP. I've heard the radio version but never seen the movie before.
