In "Yonkers Joe" (opening January 30 at the Reading Gaslamp Stadium Cinemas), writer-director Robert Celestin seems to know his way around a small neighborhood cash-stakes game of craps or poker. Watching the title character (played by Chazz Palminteri) work his magic - of inserting new cards in a deck or swapping out regular dice for weighted ones - is mesmerizing. Any time a filmmaker can give you an insider's look at a secretive world, it's a tantalizing point of view. Too bad Celestin wasn't content to stick to that world.
