In Rango, Conway played an inept Texas Ranger who had been assigned to the quietest post the Rangers had, Deep Wells, so as to keep him from creating unnecessary trouble. The Rangers apparently would have like to have removed him from the service altogether but were prevented from doing so by the fact that his father was their commander. But he seemed to bring his own trouble with him, as crime suddenly returned to a place that had seen very little of it the prior 20 years.
Also appearing in Rango was the American Indian character Pink Cloud (Guy Marks), an overly-assimilated Indian who was very fond of the ways of the whites and whose command of the English language was generally better than theirs. (Example: "Rango say him return when sun high over teepee. By that, I presume he meant that he would be back by noon.")
