Somewhat disappointingly, this concentrates on the technical aspects of film making, though the author does warn that this is the case at the outset. Some interesting quotes by and about Lubitsch, and a wee bit on one of my favorite of his actresses, Ossi Oswalda. Far too little on Pola Negri, of the same period, though the passage on why The Wildcat was not a success was interesting (too much expressionism-influenced craziness, which is one of the most marvelous aspects of the film). I was thankful for the free ebook, available via archive.org, but the MOBI version is riddled with bad OCR (nearly every 'un' is rendered as 'im'). In any case, more 'appreciated' than 'enjoyed,' and strictly for big fans or scholarly types.
