The NT production of Macbeth which I saw back in May was touring and came to Bath, and I's booked a ticket for it before I saw it the first time. I was in 2 minds as to whether or not to go, as I wasn't overly impressed with the production, but in the end, I did, and I was glad I had.
The production seems to have been tightened up considerably, and worked much better on the smaller stage in Bath than it had in the National Theatre, the smaller stage created a slightly claustrophobic feel, which worked well with the post-apocalyptic setting.
The cast also differed from the London production - Michael Nardone as Macbeth, and Kirsty Besterman as Lady Macbeth., and at the performance I saw, Banquo was played by Reuben Johnson, the understudy.
I enjoyed it more than I expected to.
