In an interview for the release of his 1983 TV movie "Thursday's Child," actor Don Murray (who played Karen's first husband) said he had kept up with the series since he left and approved of the choice for Karen's new husband. He jokingly said he wished they had gotten married in a church instead of Vegas, though. In this interview, he also confirmed that he left "Knots" to do his own series, which was not ultimately successful.
