After Twin Peaks, Kenneth continued working even through old age, in films like Survival Of The Dead to series like The Blacklist.
One of his later roles was a recurring part on Lodge 49, which was well-reviewed but flew under the radar, resulting in its cancellation in 2019 after two years.
Kenneth was still working to the end with many movies in post-production and planned to be released in the near future.
He had one son, Devon, who was the lead singer of the musical group Majical Cloudz.
