"We're home, Dad," she captioned the Vermont snap.

Despite kicking off his career in the '70s, starring in films such Deadly Hero, The Ritz and The Eagle Has Landed, the star continued acting well into his more recent years.

The veteran actor was well known for his role in teen drama series Everwood which premiered in 2002.

Williams is survived by Van Sant and their two children, 31-year-old son Gill and 24-year-old daughter Ellie.
