In the best collaboration between DiCaprio and Scorsese to date, DiCaprio seems to savor every moment playing infamous stock-broker Jordan Belfort, using words from the real man's own memoir. Harking back to Ray Liotta as Henry Hill in “Goodfellas,” Scorsese gets DiCaprio to combine comedy and madness to deliver a performance that will go down as one of his all-time best — and is his best, at least for now.
