Dillman was married for forty years to supermodel and actress, Suzy Parker, from April 1963 until her death in May 2003.
In 1995 Dillman authored a book entitled Inside the New York Giants in which he rated players drafted from the Giants since 1967; the book was penned out of Dillman's love for football, and the Giants were chosen because of their commercial popularity at the time.
Bradford Dillman is the father of actress Pamela Dillman, who is perhaps best known for her recurring role on Sabrina, the Teenage Witch.
Dillman graduated from Yale University.
Bradford: I've had a wonderful life. I married the most beautiful woman in the world. Together, we raised six remarkable children. I was rewarded with modest success in my profession. I keep busy and I'm happy. And there are a few good films out there that I might be remembered for.
