Rance Howard, Ron Howard's father, DEAD @ 89

He has one very famous son and another famous son in Ron and Clint Howard, but Rance Howard had a long and successful acting career himself.  

Entertainment Weekly breaks it down nicely:

"Howard enjoyed a Hollywood career that spanned more than six decades. Following his first credited movie role in 1956’s Frontier Woman, he went on to appear in films like 1966’s An Eye for an Eye, 1974’s Chinatown, 2000’s How the Grinch Stole Christmas, 2001’s A Beautiful Mind, and 2013’s Nebraska.

He also appeared in a number of his son’s films, including Grand Theft Auto (Ron’s feature film directorial debut), Splash, Coccoon, Parenthood, and Apollo 13.
Meanwhile on the small screen, Howard accumulated characters across Seinfeld, Diagnosis Murder, Dallas, Murder, She Wrote, Married with Children, Babylon 5, and Ron’s Happy Days.

Howard was last seen on screen in Broken Memories, a film about a son struggling with his father’s Alzheimer’s. Ron and his daughter, Jurassic World star Bryce Dallas Howard, represented him well at the premiere in Beverly Hills, California earlier this month."
