@Murk441 That’s quite an odd question really. might as well ask if you could only recommend one color film. i don’t think b/w is a factor in a film’s quality. It’s an indication of an early period of filmmaking that had no color, or an artistic choice in an age when both were available.
@davepperlmutter As a writer who grew up in the UK, but writes many books set in the US, I use which ever word the character would use, that is to say if American characters are in the book they will speak America English and if British characters are in the novel they speak British English.
