Actress Joanna Cameron, perhaps best known for starring in the cult classic 1970s live-action kids’ superhero series Isis (a.k.a. The Secret of Isis), dies at the age of 70s after suffering complications from a stroke. Launching her career in 1969 at the behest of family friend Bob Hope, Cameron at one point held the Guinness World Record for the most commercial appearances for a single actor. Following her two-season stint as Isis, she moved on to TV guest roles in The Amazing Spider-Man, McMillan & Wife, and Switch, with her last TV credit in the appropriately titled 1980 made-for-TV movie Swan Song. After leaving Hollywood, she produced and directed promotional films for the U.S. Navy, and then moved into careers in health care and hotel marketing.
