The introduction to the NYRB edition of Kaputt says that Malaperte's original draft of the Warsaw section had Hans Frank written up as the hero; obviously that would not have worked for post-war publication. I don't doubt that the man was a skillful writer, but I have little time for a historical chronicler I can't believe.
Also a) the Allies didn't go on the offensive in 1918 until August, b) were the Italians in fact fighting in the Alps after Caporetto?, c) the US Army has or had staff sergeants, but staff colonels?
If one would prefer just to watch a film set in the famous house he built there's something I saw many years ago. I think Jack Palance was one of the stars. After reading the New Yorker piece I don't think they made mention of it.
The two most wellknown films with the Casa Malaparte are Godard's "Le Mepris" with Piccoli, Bardot, Fritz Lang and Jack Palance, and Liliana Cavani's "La Pelle" with Marcello Mastroianni, Claudia Cardinale and Burt Lancaster.
This man sounds truly horrid.
