I'm fond of the movie, having watched it several times. I have even read the book and was surprised to learn that the story told in the movie has very little to do with it.
I wouldn't call the movie version my favorite ever - I wouldn't be able to say what is. But I do think that "Mrs. Miniver" is probably the most important movie about the war that was produced during the war. We've been reading in the news about the first 1,000 plane R.A.F. raids on German civilian population centers. That is pretty rough stuff for the civilians in this country to digest. I imagine people leaving the theater after watching the plucky Miniver family deal with the perils of German air raids would be less inclined to worry about paying the Germans back in the same coin. Also, since Americans are focused on the war in the Pacific, naturally enough, "Mrs. Miniver" serves as a reminder that Hitler is still the enemy and must be dealt with.
And BTW,"Homer",the work you do with your regular WWII press updates is outstanding.I look forward keenly to each one of them.
