This film tells the hilarious story of the first transcontinental automobile trip, an adventure undertaken in 1903 by Dr. Horatio Nelson Jackson. Traveling in a 20-horsepower 1903 Winton touring car with a driving partner and a bulldog named Bud, Jackson set off from San Francisco to win a $50 bet and prove that the newfangled “horseless carriage” really had a future. They splashed through streams, got stuck in “buffalo wallows,” bounced over railroad trestles, and suffered every imaginable breakdown and delay—including being towed by a cowboy and his horse—but eventually arrived in New York City 63 days later to great national applause. Tom Hanks voices the part of Horatio.
