It's a famous American book, a famous American movie, a well known and relatively successful American musical. Why would they change the spelling now? That's parochialism in the extreme.
Personaly I think we should state that the story is "too american" for the British public, relocate the story to Liverpool, and call it "The Colour Purple" - just to get our own back for "The Full Monty".
I seem to be in the minority on this Othello, and generally feel that Kinnear is much better at farce than Shakespeare.
Overall it felt like an Othello for the service industry. There was no power to the play, and no real sense of betrayal. The sequence of actions was clear enough, but I really didn't feel that squaddies with handkerchiefs were a revelation, or believable. The female roles really don't work in a hyper realistic setting, since that level of demure servility just doesn't translate unless the play is about domestic violence of a long term abused partner, why on earth would a soldier lady serve as a maid-type character to a slightly elevated squaddie's civilian wife, etc, etc
To me, the play was about a fairly snivelling Iago who wasn't interesting or complex enough to hold my interest. It would still be nice to see Adrian Lester in Othello one day....
By the time time Cassio was told that he now rules Cyprus, I couldn't help thinking that Cyprus would have him for breakfast.
