Trivia:

Before his film career ever took off, Ford worked as a carpenter, and at one point was a personal DIY/handyman to spouses John Gregory Dunne and Peggy Chantler Dick . He developed such a close bond with the Dunnes, Didion would send him autographed first editions of her books as Christmas gifts and even occasionally lend him her beloved 1969 Corvette Stingray.
