Other members of the cast are so wooden you could chop them down. Joe Armstrong as Hotspur just gabbles angrily. His wife, Michele Dockery, sounds like she's sight reading. Julie Walters and Maxine Peake are too busy trying to replace the words with acting to make out more than a couple of words at a time. Richard Eyre's use of sentimental music to tell us when it's SAD just made me LAUGH.
The brilliant performance of Jeremy Irons and Shakespeare hiding in the subtitles made it bearable at times but it was on the whole a massive artistic failure. All of this is down to the director and producers. The cast is packed with talent, misdirected in this instance. Sir Richard Eyre shares a writer's credit alongside Shakespeare (I'm not kidding) so this might tell us something about why this went so wrong. See Rupert Goold's brilliant film of Richard II (the first part of the mini-series) and compare. That's the way to do it, with clarity, nuance and a profound understanding of the play.
