Tom Hanks and Rita Wilson are active members of St. Sophia Greek Orthodox Cathedral in Los Angeles, CA. A few years back, the "Orthodox Observer" reported that Rita was a Sunday School teacher. (The church is quite large and was constructed under the leadership of Charles Scouras in the late 1940's, while he was president of Fox, if I recall correctly. Much of the construction was conducted by firms that worked for Fox and were encouraged (or coerced) into donating or significantly discounting their work;---he must be a grandson, but I see the name Charles Scouras as a producer of Desperate Housewives.) (These threads get long and many don't read the older pages--most of the names in the prior seven comments have already been covered above.)
I'm not sure to which parish they belong, but Troy Polamalu and his wife's marriage was celebrated by GOAA Metropolitan Maximos, formerly of Pittsburgh. I saw on facebook, soon after his enthronement in December, Metropolitan Savas of Pittsburgh was Polamalu's guest at a loge for a Pittsburgh Steelers game.
