The Lords of Flatbush (1974)

The Lords,  a gang of four brooklyn youts (not youths) in 1950's Brooklyn, find themselves facing adulthood.   This movie is a treat-- a young, pre-rocky Sylvester Stallone steals every scene he's in playing meathead Stanley.  Perry King is Chico the playboy, and pre-happy days Henry Winkler as Butch.  Imagine a darker, neurotic Jewish Fonzie.  Some very memorable scenes in this one-- Stallone in the store buying a wedding ring for his girlfriend is priceless.  See it.
