Buck Henry will appear after the June 8 performance. Dick Cavett is set for the June 15 show. And Robert Osborne will speak following the June 22 presentation. Henry, who has split his career between screenwriting ("The Graduate," "To Die For") and acting ("Short Cuts," the Off-Broadway play Three Viewings) acted with Orson Welles—one of the characters in Pendleton's play— in the film "Catch 22," a movie which also starred a young Pendleton.

Welles was a frequent guest on Dick Cavett's famous talk show of the early '70s.

Susan Bennett, John Judd, Sean McNall, Lee Roy Rogers, Jeff Still and Ian Westerfer currently star in Orson's Shadow.

Orson's Shadow plays the Barrow Street Theatre, 27 Barrow at Seventh Avenue South. Tickets for the production are priced $55 and are available by calling (212) 239-6200. For more information visit www.OrsonThePlay.com.
