Actor Paul Petersen II first shared the news on Facebook. TMZ confirmed with law enforcement.
Neighbor Bev Washburn, who co-starred with Kirk in the movie Old Yeller, notified Petersen. Kirk played a boy who befriended the title dog in the 1957 tear-jerker.
Born Dec. 10, 1941, Kirk also appeared in films The Shaggy Dog, Swiss Family Robinson, The Absent Minded Professor and its sequel, Son of Flubber.
Kirk continued to act in film and television regularly until 1975’s My Name Is Legend. His last credit was the 2001 horror film, The Education of a Vampire.
Petersen wrote that Kirk lived alone and was estranged from his blood relatives because he was gay. Petersen said he and Kirk’s friends would handle final arrangements.
“Please know that Tommy Kirk loved you, his fans,” Petersen wrote. “You lifted him up when an Industry let him down in 1965. He was not bitter. His church comforted him.”
