Character He Plays: Mr. French
Boston Guy's Assessment: He doesn't really have much of a Boston accent. It's more Irish/English-sounding.

Yeah, so here's the thing: it's up for debate whether Mr. French is supposed to be from Boston. Ray Winstone is English, and at one point Mr. French does say "Slainte," the Gaelic word for "cheers," so it might be safe to assume that Mr. French is from across the pond. That being said, he still has a better Boston accent than Martin Sheen or Vera Farmiga.
