Turk 182 (1985)

Not quite as good as I remember it, this urban warrior flick has a young Timothy Hutton seeking compensation for his injured fireman brother by a succession of more and more outrageous pranks, planned to shame the New York mayor who is seeking re-election.  His is a bloodless attack - mainly a series of outlandish graffiti (his handle is Turk 182.)  By the end, even the corrupt mayor is rooting for him as he captures the hearts of the citizens. The director was Bob Clark, best known for the infamous "Porky's", but don't hold that against him as he also directed "A Christmas Story" which is something of a classic.
