In terms of the stars, the only ones I cast were Billy Connolly and Pauline Collins. I was in Los Angeles working and a lot of this took place on the telephone. I'd met Maggie [Smith] once and I'd come back-stage, which I'm usually loathe to do because as an actor you don't want people coming back because you want to get home [laughs].
