There is a new trailer for Capel Green, launched for the New Year, four months before the film's premier, see: https://www.youtube.com/watch?v=cB67Sh3kNDw. It is different from the others because it portrays the Rendlesham Forest Incident in a larger context, part of the general UFO phenomenon. It also includes clips from news stories from late 1980, showing how turbulent and uncertain the world was then. The Solidarity trade union had come to power in
and there was the threat of a Soviet invasion. For a while war was imminent. I
think this may have been why UFO's appeared at nuclear weapons bases. The
release date for Capel Green is May Day
and it now has an IMDB page, see: https://www.imdb.com/title/tt8151794/. Poland
