Family
Badham is the older brother (by 13 years) of Mary Badham, Oscar-nominated for To Kill a Mockingbird. Brother and sister have never worked together on the same project, however. Though she's younger, all of Mary's acting credits preceded John's film/television credits by several years.
John's former wife is veteran model Jan Speck, 15 years his junior, of The New Treasure Hunt fame. She has had assorted cameo roles in many of his projects, starting in the 1980s.
