Ummm LOL they're both different movies!
Liberty Heights was an R-rated movie that came out a few years ago that was basically about a Jewish family in the 1950/60s (something like that), and one of the sons is friends with a black girl (much to his parents dismay), and things like that. It's really good.
L.I.E. was an NC-17-rated movie from last year that is basically about a 15-year old boys sexual awakening near the Long Island Expressway, where his mother was killed. The movie should have been rated R, but the general themes (there is a pedophile in the movie) it was rated NC-17.
Both good movies.
