Joan Van Ark & John Marshall — 54 Years
Joan Van Ark has come a long way since playing the role of Valene Ewing in a CBS sitcom called Knots Landing. Throughout her incredible career, Joan has been featured in many different shows, including Hawaii Five-O, Temperatures Rising, and The Rockford Files.
After meeting John Marshal (who just happens to be a former KNBC-TV reporter), Joan and John decided to exchange wedding vows in 1966. And while the two of them have faced some problems in the past, they have successfully dealt with them. They have been married for 54 years now.
