I was busy watching Goblet of Fire when I got the idea for the poster. The photos are from production stills or from publicity photos of the actors. The large Triwizard cup is from a production still (a really good one). The mermaid and "old style" art are from a couple different sources for which I have license. The fonts are from various collections and are used with license. The old-style page elements are from InkyDeals, I think.
