I began my evening watching the remaining special features on the Criterion NIGHT AND THE CITY DVD. There were two interviews with director Jules Dassin, filmed many years apart. In the earlier of the two (looks to be in the 1970s), he does talk about his MGM years and the McCarthy period though when the conversation turns to discussing his former friend Elia Kazan, he cuts the interview off.
The other filmed much later is more about NIGHT AND THE CITY.
I enjoyed both of the interviews.
There was also an excellent documentary on the two different scores written for the film and excerpts down of the scenes with the two different scores. Amazing difference in feeling depending on the music (or lack thereof).
I also started the film over and watched about 12 minutes of it with Glenn Erickson's excellent commentary track running. He has a very pleasant voice for a commentary track, and he's so knowledgeable that it makes listening a real pleasure.
