This is a well-intentioned version of Macbeth meant primarily for educational purposes. The sets are extremely simply, but this is not the problem. First of all, the witches - always a special problem with Macbeth - seem to come straight from an undergraduate modern dance class, and appear to be clad in crepe paper streamers. The major problem is, however, that they are difficult to understand. Poor Piper Laurie as Lady Macbeth, normally a reliable actor, is saddled with an embarassing genital-grabbing scene during the "unsex me now" soliloquy, and Jeremy Brett with some silly hip-swiveling in a later scene. I can only blame the director here - these are two perfectly competent actors not generally known for lapses in good taste. And there is a good point in this production - the delivery of many of Jeremy Brett's lines are really wonderful, with a lovely flexibility that could make the story make sense to an audience who has perhaps only read the play, or heard the lines read in a very stilted de-dum, de-dum fashion. Just as an example, note his handling of the "Is this a dagger I see before me" soliloquy, and his very persuasive exchange with Banquo's assassins. However, after about act 2, there is entirely too much yelling. I'm also inclined to point a finger at the director for this, since Brett almost always used his wonderful voice to best effect when given his head. Macbeth also, for no reason I can see, spends the last act with a large stick down his back. What's that all about?
All in all, probably worth having for educators (although expect your class to break into giggles in a couple of the unfortunate scenes mentioned above), Shakespeare collectors and friends of Jeremy Brett.
