The DrsC just started watching another "beginning of World War II" drama on PBS, this one entitled World on Fire. It appears to follow the lives of various Brits, Poles, French and Americans living in Europe as Germany moves into Poland, kicking off the actual declared war.
I presume it will show how their lives eventually intertwine in interesting and potentially tragic ways. The original season has seven episodes, and the Internet claims another season has been funded. The war dragged on for six years and a lot of episodes can be written, supposing an audience is available and interest is maintained.
The series is available for streaming (if you subscribe) at the PBS archive. When we finish season one I'll write a review.
One of these days we'll go back and rewatch the granddaddies of all WW II miniseries: Winds of War and War and Remembrance. These were based on novels by Herman Wouk and starred Robert Mitchum and Polly Bergen as USN Captain Pug Henry and Mrs. Rhoda Henry, plus Ralph Bellamy as FDR and Robert Hardy (aka Minister of Magic Fudge) as Churchill in the second series.
