The character of Lyle in Napoleon Dynamite is an old farmer and also a local minister with a vocal delivery that is something between a speech impediment and an extreme redneck mumbling. I am just curious if the actor who played him actually acted that vocal delivery out or does the guy really talk like that in real life.
The movie was filmed in Preston, ID and this man is a local who has acted in several films from Mormon film makers. I have a number of friends from Preston who know him and have told me that this is how he talks, although I believe it was somewhat exaggerated for this film.
I am from Preston Idaho and helped Mr Critchlow run his farm for several years. What you see in the film is pure Dale Critchlow.
