I own all three modules of the Quest for Immortality series, but haven't yet got to use them. However, I've read them extensively, and though I've owned them for something like a year now, this never crossed my mind.
City of Golden Death:
In the City, a trap activates that will flood the city with molten gold created by the Jewel of Everlasting Wealth. Now I literally just got done watching Aladdin with my nephew, and I can't help but wonder how much of this module was inspired by the Cave of Wonders? The whole, 'fantastic wealth that you can't have lest the place be flooded with lava/molten gold' thing is pretty similar.
If my observation is true, that's awesome. It's my favorite movie from that company and I love that Paizo can use things like that for inspiration.
