That was Robert Aldrich. And that [Emperor Of The North] was one of the only times I actually got a part in a movie in the conventional way: The role was there, I auditioned, I auditioned again, and then I actually did a full-fledged screen test, which they shot on a soundstage on the lot at 20th Century Fox. They put up a set, and Robert Aldrich actually directed me in this screen test.
Around '75 when the recession hit, club owners started going to disco because it was cheaper for them to just buy a sound system than it was to hire a band.
