As “unfilmmable” as a movie about men lost in words, attempting to write a dictionary might seem, there is a better picture in this subject, based on journalist/history buff Simon Winchester’s best selling book. Limiting its scope, beefing up the connection between the “consanguineous” correspondents, their letters and their meetings, giving the two men competing agendas (acceptance by academia vs “redemption”) rather than shoehorning both of them into one and losing the “love story” would have been a start.
