The single largest cost on the movie was for the rain effects throughout the first half of the film.
During filming, members of the cast who weren't required to be on the set certain days would show up anyway to watch the other actors' performances.
During the production, the actors referred to this film as "Death of a Fuckin' Salesman".

After Al Pacino saw Kevin Spacey perform onstage on Broadway in "Lost in Yonkers", he brought director James Foley along to see the actor for himself. This led to Spacey landing his role in the film.
