Every journey has a beginning, and the beginning of A Big Bold Beautiful Journey is a car rental agency run by a strange cashier and a mechanic, played by Phoebe Waller-Bridge and Kevin Kline respectively. The odd pair offers character David (Colin Farrell) a 1994 Saturn GL, a car way past its prime, insistent upon adding a retro GPS with the package. It’s this vehicle that propels David, joined by Sarah (Margot Robbie), a stranger he met at a mutual friend’s wedding, on A Big Bold Beautiful Journey.
