On an average of once every two or three seasons Britain's prestigious Royal Shakespeare Company of stage players reluctantly surrenders one of its own to feature films.

In 1973 it is Sara Kestelman who stars as a prophetess in the year 2293 in John Boorman's "Zardoz," a 20th Century-Fox release premiering ....................... at the ...........Theatre. Sean Connery co-stars.

Sara comes from good strong stock, theatrically speaking: the Central School of Speech and Drama, London; the Liverpool Playhouse and Library Theatre, Manchester. At the latter pair she slipped neatly from "The Physicist" into "The Crucible," then changed direction again for "The Importance of Being Earnest."

Sara joined the Royal Shakespeareans in 1969, staying four years. The culmination of her time there was the performance as Titania in the towering Peter Brook Production of "A Midsummer Night's Dream."

"Zardoz" is her first film.
