OK, for those who own For Keeps, here is the "new" content:
from I Lost it at the Movies -- "The Glamour of Delinquency" from Kiss Kiss Bang Bang -- "Marlon Brando: An American Hero" from Going Steady -- "A Sign of Life [Shame]" from Deeper into Movies -- "The Fall and Rise of Vittorio De Sica [The Garden of the Finzi-Continis]" from Reeling -- "Cicely Tyson Goes to the Fountain [The Autobiography of Miss Jane Pittman]" from When the Lights Go Down -- nothing new from Taking It All In -- "Hey, Torquemada [History of the World, Part I]", "Up the River [Fitzcarraldo, Burden of Dreams]" from State of the Art -- nothing new from Hooked -- nothing new from Movie Love -- "Unreal [Women on the Verge of a Nervous Breakdown]"
Also, For Keeps includes excerpts from the essays "Notes on Heart and Mind" (from Deeper into Movies), "Politics and Thrills" (from Reeling), and "Notes on Evolving Heroes, Morals, Audiences (from When the Lights Go Down). The Age of Movies table of contents includes these essays as well, but it is unclear whether they are the entire essays or the same excerpted content as previously published.
There is also a new introduction by Sanford Schwartz and also an early Kael essay titled "Movies, the Desperate Art" from 1956. Pretty slim pickings, all in all.
