Interesting. Roxanne (Haley Bennett) and Christian (Kelvin Harrison Jr.) are shown singing in the trailer, but not Cyrano (Peter Dinklage).
My pet peeve about period films: When actors don't sound like they're in the same time and place. Bennett and the actress playing her mother have accents that sound British, but Harrison and Dinklage sound so contemporary and American. (The art direction, however, looks Oscar-worthy.)
