Silent film fans will enjoy Kevin Brownlow's account of silent film "The Parade's Gone By". It's not so much a linear history as a look at the pieces of the pie. Directors, producers, actors, cameramen, stuntmen, even inter-title writers.
He notes that acting was all over the map, good and bad, from the start and that audiences and critics noticed it. There were many complaints about bad acting in silent films even during the silent era.
Simon, I don't know how mobile you are, but it is rumored that Abel Gance's "Napoleon" will be playing in London in 2013 and you must get to see it if you can. I went to California to see it in March and there are not superlatives to describe the way it overwhelms you. Kevin Brownlow and Carl Davis have put together a first-class presentation with live orchestra and the biggest screen you will ever see.
