John Paulk and his wife Anne appeared on the cover of Newsweek magazine in 1998 as the face of Christian ex-gay therapy. In “Pray Away,” a wide-ranging documentary from director Kristine Stolakis, Paulk is interviewed today, and he is unrecognizable as the man on that cover. Even though he was much younger when he posed with his wife, the contemporary Paulk looks so relaxed and comfortable with himself that it really is like looking at a totally different and much more appealing person.
