James Madio (“Hook,” “The Basketball Diaries”)—a Bronx-born, now Ohio resident—gives a knockout performance in this biography of Willie Pep, a retired featherweight boxer out of Hartford, Connecticut whose glory days are behind him (a 220-10 record!). But now it’s 1964, money is tight, and it just might be time to un-retire. Featuring supporting performances from Stephen Lang and Ron Livingston.
