I have written a bit about the 5 Hollywood directors who went to the front lines both in the Pacific and ETO for WW2.
And I reviewed the work of one of them, William Wyler, with the brilliant restoration of his unused film in making his Memphis Belle. There is more to write about these 5 fascinating directors, but suffice it to say there is a nice Netflix documentary, with commentary by 5 contemporary famous directors, on them.
That has to be a future post for me.
In the meantime on the F/B page, Hogday posted a fascinating video from George Stevens on Germany right after the war.
