I seem to making a habit of posting about theatre trips! Went to the National Theatre in London to see The Motive and the Cue.
This was about the staging of Hamlet on Broadway in 1964, starring Richard Burton and directed by John Gielgud. It was really about the way the two clashed during 25 days of rehearsals - Gielgud's interpretation was very mannered and formal (he performed Hamlet 500 times!), and Burton's was fiery and emotional. They eventually found mutual respect.
Directed by Sam Mendez, and starring Mark Gatiss as Gielgud, Tuppence Middleton as Liz Taylor and Johnny Flynn superbly as Burton.

What is interesting is that Flynn is the same age as Burton was in 1964, and Gatiss at 56 is almost the same age as Gielgud, who was 60 in '64. Likewise Middleton - Liz Taylor was 32 and Middleton is 36. So the ages of the main characters were very true to life.
