If you are looking for celebrity images as an extension of seeing how the other half live, take a look at this commercial image library: WireImage.
A search for Michael Mann brings up a wealth of images of many of his public appearances. I was surprised to see he did a book signing for his Taschen book in 2006. I have the book and recommend it. Curiously, it doesn’t seem available any more, even from Taschen’s own website. You cannot buy it new on Amazon, though some resellers have it still. Not sure the reasons why. Perhaps it peaked in its demand.
