As a guest on Inside the Actors Studio (1994) (Oct. 2, 2006), Al Pacino recounted to host James Lipton how he'd had an embarrassing moment in a crowded elevator after winning his first Oscar. Unbeknownst to Pacino, was that the head of his statuette was poking a well-known actress in her posterior. When she turned around, Pacino quickly explained that his Oscar, not he, was to blame for her discomfort.
Philip Seymour Hoffman auditioned for his role five times before he was cast.

Frank's bizarre habit of yelling "hoo-wah!" is an actual United States Army battlecry, although he is saying it wrong. He places far too much of a "W" sound on the second syllable. The real version is closer to "hoo-ah!"
There seems to be some confusion between the terms "hoo-ah" and "oo-rah." "Oo-rah" is a United States Marine Corps expression with a completely separate history from the United States Army expression "hoo-ah." "Hoo-ah" derives from the acronym HUA which stands for "Heard, Understood, Acknowledged." Over the years this phrase has taken on many meanings to US Army personnel including; "understood?", "thanks", "I'm not listening to you", "go away", "you're a moron", "excellent!", "shut up", etc. For the origin of the Marine expression "oo-rah"... ask any Marine. They all know, and they'll be happy to explain it.

During the meeting of Baird's Disciplinary Committee, in the background on the wall of the great hall can be seen the next quote: "The place where people meet to seek the highest is holy ground".

An adaptation of Giovanni Arpino's novel "Il buio e il miele", the movie actually shares with the book only the basic premise (young man accompanies on a journey a blind ex-officer who is bitter, charismatic and strong-willed).
