I'd not seen this before or heard mention of it:
Dare to Dream was directed by Marianne Jenkins, a film student from Goldsmiths' College, University of London, in 1990. It looks at the history of anarchism in the UK and beyond, as well as the state of the movement in the tumultuous year the poll tax uprising finally led to the resignation of Thatcher. Among the anarchist heavyweights interviewed are Albert Meltzer, Vernon Richards, Vi Subversa, Philip Sansom, Clifford Harper and Nicholas Walter, as well as a host of lesser known but equally committed dissidents. The film also features the miners strike and class struggle, squatting and social centres such as Bradford's 1in12 club, animal rights and feminism.
Seems to capture the spirit of the times reasonably well which means there is a lot of Chumbawamba on the soundtrack and quite a bit on animal rights, punk and so on. But the footage of Meltzer, Sansom, Rety etc is well worth a look.
