2493: Opposites

Two contrasting film stars allegedly said ‘1A’ (five words) and ‘49/27’ (six words in total). Remaining unclued lights (including one of three words and two pairs) give the birthplace of one and the place where the other died and the titles of two films in which they starred. Solvers must shade the two clued lights that give their surnames. Fifteen special clues include a definition and a hidden letter mixture of the light. Ignore two apostrophes and two accents.
