Pride film trailer analysis- NATIONAL/REGIONAL identity

The first shot of the trailer is a black screen establishing location, 'in a small Welsh mining village', then an establishing shot showing the misty Welsh land, then another black screen saying  'deep in the valleys' which is how Wales is often referred. Further shots of Welsh countryside, shown to be misty and grey. Then we see some interior shots of the community hall where the people eat together and all appear to know one another, a stereotype of small towns. The gay group are shot from a worm's eye view to show the power they will have over the destiny of the mining community. The reaction shot of the elderly lady shows this town and its residents are unused to trendy gay people, which points to the stereotype of small rural towns as being old-fashioned and conservative. The gay group members' own apprehensive faces show that they are ware of the possibility of awkwardness between the conservative villagers and their group. As a member of the LGBT+ community even today, entering small villages full of elderly people is intimidating, so in the 1980's this would have been more pronounced. The next shot of the silent community hall full of stone-faced villagers looking at the gay group shows the divide in this country between metropolitan trendy forward-thinking LGBT youths and older more traditional conservative types. The next sequence of the main characters in the kitchen is further reinforcing this, as the villagers stand on one side of the kitchen and the gay group stand on the other. This is when the difference in their mode of dress is obvious, as the villagers wear earthy shades and corduroy and have sensible, natural hair, whereas the gay group have styled hair, some dyed and they wear more trendy clothes. This use of mise-en-scene makes it easy to differentiate groups, even for someone unfamiliar with the characters.
There is then a letterboxed shot of a white background with red text telling the audience that it is based on a true story, which would make it more interesting for a British (especially Welsh) person to watch, as they may be unfamiliar with the story and will want to find out more OR they could remember the events and wish to relive them via the media of film.
The rest of the trailer serves to show off funny parts of the film to draw in audiences and plays on stereotypes of the British gay scene in the 1980's being vibrant and fun, as the old Welsh women seem to have a rollicking good time dancing in the gay club. This segment also plays on the stereotype of the British gay scene (and British people in general) being very chilled, as the elderly village women seem to have no qualms with being surrounded by men in bondage gear.
When the characters return to go to bed, the young women and the elderly women share bed space and laugh together about sex toys, which comments on the tendency of women being more open with one another about personal matters, while the men are downstairs wishing for some peace and quiet.
