A historical advisor is a loose term for the person on set who makes sure all of the vast many details (and it is a vast many- looking out for conduct, clothing, props, titles, and speech to name a few) are all in proper order. If something is out of place, for example a loaf of bread is caught on camera while it is still in its plastic wrapping from the store or a character uses the word 'boyfriend' before it came into popular conversation (both are example of minor errors in past period drama films), then everyone swoops down on the mistake and criticizes it. The goal of a historical advisor is to make sure nothing is out of line take after take, one of the many jobs that go unnoticed by the audience if done perfectly because we are completely drawn into the era of the film.

In his spare time, he seems to have recently taken up the role of being a historical advisor. He has over seen The King's Speech (technically his title for this movie was Military and Ceremonial Advisor) and another recent work of Julian Fellowes' The Young Victoria as well as every episode of Downton Abbey.
