Sean Bean is playing Brian Braddock... in a Leviathon-central role in all 78 of the Scorcese-directed, "The Uncanny X-men" movies... Sean Bean I think most likely is twice the age of Kiera Knightley's.. of all the actresses who are Kiera Knightley... but Kiera Knightley is playing "Betsy Braddock"... Brian Braddock's (Sean Bean's) .. twin sister.. Betsy Braddock.. in all 78 of the Scorcese-directed, "The Uncanny X-men" movies.. so .. can that work.. also .. Brian Braddock most likely would have a clipped, british accent.. exactly like Alan Rickman's.. I wonder ... does David Smuchler.. (.. sorry.. am I spelling his last name.. accurately.. is it.. David Smuckler..?..).. does he teach British accents..?... Kiera Knightley's character, Betsy Braddock is also possessed of an upper-crust, british emma thompson ... kristen scott thomas-like british accent...
