This is it. This is my goofy little favorite Dream.
This is the 1968 Peter Hall/RSC production and it is a glorious mess. Technically it's a shambles: the audio and video quality are fairly atrocious. However, the performances are golden. Helen Mirren and Diana Rigg are probably my all-time favorite Hermia and Helena, and there is no scenery because Ian Holm has eaten it.
