Quoted from Hitch9:
I don't think so. I think that the 75th anniversary of WOZ, was just the icing on the cake, and helped validate that this was the right decision to make. I agree with you sunfox, that the huge success of the coin pusher was probably one of the main factors behind the decision.
I believe Jack's even explained several times in detail how he picked WOZ. Despite the coin pusher and its wild success, I don't think WOZ was his default "no brainer" choice for a pinball. He's talked about asking one of his employees to present him with a list of available licenses, and when he saw his choices and noticed WOZ on the list, he said gimmie that. And the employee went, "really?"
Clearly at that point it made a lot of sense to Jack especially with his prior history, and it fit with his goal of being family-friendly, recognizable and timeless. If you can't stand the 75-year old movie for whatever reason, then just pretend it's some original theme starring a lonesome teen girl caught up in a horrific natural disaster, tormented in a strange land by green witches and swarms of flying monkeys, accompanied by a cast of bizarre magical characters ruled by a con man king, featuring murder, drugs, kidnapping and chemical warfare, all wrapped up in a battle of good vs evil.
Hmm. WOZ is too family friendly?
