An Empire of Their Own: How the Jews Invented Hollywood
“That subtitle may inspire in some readers waves of ethnic pride, and in others waves of ethnic revulsion, but the point of this book is that its claim of origin is quite literally true.
And what makes it an interesting read for political types is the way it demonstrates that no matter how much the founding Hollywood moguls and their successors tried to peddle an idealized, escapist form of entertainment, bubbling up under and around their every project was ideology, racism, ethnic prejudice, class friction, domestic and international politics and all the other raw, seething stuff that distinguishes this country from all others. In Gabler's hands, the Industry draws a picture of American political history in spite of itself.”
“This is an excellent, well researched book about the men who invented Hollywood and the movies according to their own ideas about what the American Dream should be and what their ideal of America might look like.”
