The movie, as formulaic in its way as Rocky or Rudy, is buoyed by its good acting and by its entirely new portrayal of a grown man who stutters: Colin Firth's King George gulps and strangles himself trying to get the words out, yet retains his dignity and invites our empathy. For the 1 percent of the population that stutters, and has withstood the additional ignominy of watching stuttering characters in Hollywood films, the movie is a rare catharsis. A likable king struggling to speak is significantly more attractive than the violent criminals (Taking of Pelham 1-2-3, Primal Fear), or abused, suicidal inpatients (One Flew Over the Cuckoo's Nest) of yore.
Slate has a slide show of video clips from movies that address stuttering, but even more interesting is their short history of attempts to cure stuttering. Link -Thanks, Jocelyn!
