Smith, who worked with Parks on films like Tusk and Red State, wrote a touching tribute to the actor on social media.
"I hate to report that my cinematic muse #michaelparks has passed away. Michael was, and will likely forever remain, the best actor I've ever known," Smith shared. "I wrote both #RedState and @tuskthemovie FOR Parks, I loved his acting so much. He was, hands-down, the most incredible thespian I ever had the pleasure to watch perform. And Parks brought out the absolute best in me every time he got near my set."
Parks was perhaps best known for his roles in Quentin Tarantino films like Kill Bill, and Django Unchained, but broke into the industry in the early '60s with TV roles on Zane Grey Theater and The Untouchables. In the early '90s, Parks starred in Twin Peaks and Walker, Texas Ranger.
Parks is survived by his wife, Oriana, and his son, James, who starred as his on-screen son in From Dusk Till Dawn and Kill Bill.
