The prime-time soap "Dallas" celebrates its 40th anniversary this week. The drama about the Ewings, a Texas oil family with its share of issues, became a sensation in 1980, when viewers were asking, "Who Shot J.R.?" "Dallas" ended its run in 1991, so where are the stars of the show today? Patrick Duffy played Bobby Ewing on the show. He lives in Oregon, and is a practicing Buddhist. Victoria Principal, who played Pamela Barnes Ewing, launched a popular line of cosmetics, called Principal Secret.
