You can’t go by the trailers, which suggest a flat-out satirical comedy. Trailer cutters always go for the socko stuff, the lowest-common-denominator defaults. But if it’s more or less a huge sprawling black comedy (and I say “if”), that may amount to a brilliant approach. Scorsese, screenwriter Terrence Winter and star Leonardo DiCaprio came to the Wall Street table way too late to play it as some kind of dark, solemn, high-stakes melodrama. The last 25% of Goodfellas (arguably the best part) was pure cocaine in the veins. Well, cocaine and then the comedown.
