Cole has roots in one of Hollywood’s founding families, as his mother was the granddaughter of Harry Warner – one of the four founders of Warner Bros.

Cass wrote the biography The Brothers Warner: The Intimate Story of a Hollywood Studio Family Dynasty.

It was published on June 12, 2008, following a 2007 television documentary of the same name that was written, directed and produced by Warner.

While creating the two projects, Cass founded her own production company called Warner Sisters.

She was a proud grandmother to Cole’s three children: sons Ryland, 19, and Colt, 15, and daughter Steely Rose, 11.

In her Instagram profile, Cass described herself as a “3rd generation filmmaker, author, mother, Nona, concerned citizen” and “Rip’s mother,” referring to son Cole’s Yellowstone character.

Her most recent post was from January and showed her grandsons.

‘Can you hear we have the future! Good souls get in line. So proud of them: Ryland and Colt. A job well done by Mr. Cole and dear Cynthia!’ she captioned it.
