Trivia: The prop department had some fun during the making of the movie; you can see a lot of names of miscellaneous crew slipped in a few spots. There are boxes with case files scattered around the district attorney's offices; the ones behind Willy in his own office (People vs. Bonaventura - Tony Bonaventura being the property master, People vs. Morgenthau - Kramer Morgenthau being the director of photography) get quite a bit of screen time, but there are several others all over the office space, all carrying the name of a crew member. For instance, in a brief sequence when a dejected Willy walks up to Mona's desk to ask for her help before the third act, you can see unique ones. There's also a listing board with judges during the arraignment, and one with doctors when Willy is stopped by the hospital security; both of them are filled with names of production crew members.
