He Was a Quiet Man is a 2007 American black comedy drama film, written and directed by Frank Cappello.
On one particularly bad day, Bob is about to go on a murderous rampage when his coworker, Ralf Coleman, beats him to it, shooting up the office and killing several people.
He finds Venessa, a pretty executive he has never had the courage to talk to, wounded on the floor, and saves her life.
The former invisible nobody is suddenly thrown into the spotlight of public notice, and he is considered a hero by those he wished to murder.
His boss, Gene Shelby, promotes Bob to "VP of Creative Thinking" and gives him all the perks of higher management.
The last scenes show police searching his house to find a note that reads, "You may ask why I did what I did... but what choice did you give me?
As Bob's vision fades to black and he sees Venessa mouth the words "I love you," a faint beeping sound is heard.
Bob removes a notebook from his desk drawer, and notes that today, Venessa loved his hula girl.
The image pans out to reveal a meticulously detailed log of all inconsequential events and interactions with Venessa over the course of months (or even years).
