When Kimble hops a freight train and meets Homer, the latter starts singing some lines from "Engine 143", a traditional folk ballad.
Adjusted for inflation, the 10 cents that Kimble pays to read the newspaper would equal approximately $1.00 in the year 2022.
Hampton Fancher, ironically playing fugitive Marty Macklin, gives his name as Homer and that he's a writer. Kimble, resorting to the name Jack, compares Homer's voluminous cache of writing to the "Odyssey," the ancient epic poem, composed by another Homer, about a man on a 10-year journey to find a way to get back home.
Gerard tells Dr. Ryder that Kimble was once in a town called Drain in Oregon. Drain, Oregon, named for its founder Charles Drain, is a small town in Douglas County about 50 miles east of the central Oregon coast.
Dr. Kimble uses more than one alias here. He starts out as Jack Davis, then assumes the name Bob Grant, briefly goes back to Jack, and ends up as William Smith.
