Yes, Glen Campbell's character did die in the 1969 movie version and there is an interesting blooper when last we see him. After LaBoef helps pull Mattie and Rooster out of the snake pit by using his horse, he tumbles off of the horse and onto the ground and dies. His legs are crossed - yet when Rooster and Mattie ride away and the camera looks back; his legs are uncrossed.
I want to use this forum to say that the recent remake by the Cohen Brothers of "True Grit" was a good movie, but my opinion is that John Wayne made for a better Rooster Cogburn. That's not meant to detract from Jeff Bridge's rendition but I just think that John Wayne's age (61 at the time) made for a better character.
