The longest interval in theatre history continues. Last week the National Theatre livestreamed a 2018 version of The Madness of George III produced by Nottingham Playhouse with Mark Gatiss in the title role. The script, written by Alan Bennett as a response to King Lear, is much easier to like than the original. An engaging family comedy, with a sad bit in the middle, it benefits from a wonderfully happy ending. The good king is cured, the bad doctors are vanquished, order is restored. A real crowd-pleaser. Bennett’s research gives it the feeling of a documentary drama as he examines the difficulties faced by monarchs who wielded real political power.
