(This might be the last post for May. Round numbers and all that. There are a couple of new posts on Poul Anderson's Cosmic Environments.
If Poul Anderson's Dominic Flandry series were to be filmed, then one actor would have to play the central role in Ensign Flandry and A Circus Of Hells but one, and only one, other actor would be needed for the rest of the series. This is because Flandry changes his face by "biosculp" but then retains the second face for the rest of his life. First, he does not get around to changing it, then, when he is older, it becomes unfashionable to do so.
His face in his sixties was a...
"...relic of a period when everybody who could afford it got biosculped into comeliness. (The present generation scorned that; in many ways, these were puritanical times.)"
-Poul Anderson, Flandry's Legacy (New York, 2012), p. 31.
We expect technological advances but Anderson also presents changes in fashion and morality.
In The Rebel Worlds, when Lieutenant Commander Dominic Flandry reports as ordered to Vice Admiral Sir Ilya Kheraskov, the Admiral, who has never seen Flandry before, says, "'I see you have a new face.'" -Poul Anderson, Young Flandry (New York, 2010), p. 383. Flandry's identity had been verified by a machine when he entered the building. This would make a good scene in a film. The cinema audience would have noticed that a new actor was playing Flandry but would not expect another character to comment on the changed face!
