An unname actor was playing the role of an "Arab sheik" in Hollywood when the First Doctor, Steven Taylor and Sara Kingdom materialised in the Doctor's TARDIS. He was discussing his scene with a vamp with film director Ingmar Knopf when the TARDIS crew interrupted them. (TV: "The Feast of Steven" episode of The Daleks' Master Plan)
