Another period drama will grace our TV screens tonight, it seems people just can't get enough of them considering the success of Downton and Mr Selfridge and the like. The Crimson Field will follow the brave doctors, nurses and volunteer women working in First World War France, patching up soldiers wounded in the trenches. It will star Oona Chaplin, who people will know as Talisa from Game of Thrones, where she ALSO played a nurse patching up soldiers....hmmm, unusual typecast to get really isn't it?
