This should be shown in every English-speaking school in the world. Excellent introduction to Shakespeare: part documentary, part dramatization of key scenes in Richard III; often hilarious, always illuminating.
The lines used at the beginning and end of this film are from The Tempest, IV:1, spoken by Prospero, and anyone who so desires can read them at my funeral:
Our revels now are ended. These our actors,
As I foretold you, were all spirits and
Are melted into air, into thin air:
And, like the baseless fabric of this vision,
The cloud-capp'd towers, the gorgeous palaces,
The solemn temples, the great globe itself,
Ye all which it inherit, shall dissolve
And, like this insubstantial pageant faded,
Leave not a rack behind. We are such stuff
As dreams are made on, and our little life
Is rounded with a sleep.
Here's Gielgud's version from Prospero's Books, followed by another great soliloquy from the play...
