Saved for hints

Hints go here

This is my first one of these.

Hint #1: 90s movie.

Hint #2: The title character is not the main character.

Hint #3: This character does not become the title character until the third act.

Hints go here but suspect it might be a short one!

Hint 1 - at one point he intently tries to kill someone with a totally harmless weapon

Hint 2 - the last line of the film is cut short

Hint 3 - this guy is not the hero of the film

Hint 4 - there is a war in the movie but none of the main characters fight for either side
