Ever since I was a young boy I played the silver ball. And needless to say I was very excited when I found out they were making a movie rendition of the Who's classic rock opera Tommy. I was even more excited that Elton John (pinball wizard) would be squaring off against Roger Daltry (Tommy) during Pinball Wizard to determine who would be "The Bally Table King"
Much to my surprise when that scene came, these weren't Ballys at all, but two ten year old classic Gottlieb wedge heads. Tommy was playing Kings and Queens and Elton a modified Buckaroo.
Now most of us know the makers of this movie partnered with Bally to make the highly successful first licensed game Wizard! that sold over 10.000 units and the even more successful sequel Captain Fantastic, but it has never been explained to me why Ken Russell and the Who went with Gottliebs during that pivotal scene.
