Tiger users were able to use and download the widget from MacAmour.
But it seems it stopped working.
So here’s the how to fix it, then you’ll never get the “invalid zip code” error message again.
Recently the Leopard Movies widget, which Steve demoed along with Leopard, stopped working in Tiger. Leopard’s built-in Movies widget continues to function, while in Tiger, it gives an error of “invalid zip code.” You can make this widget function once again in 10.4.

Navigate to /Library/Widgets and find the Movies widget. Control-click on the widget and choose Show Package Contents from the pop-up menu. Then open parser.js in your favorite text editor, and replace all occurrences of A99D3D1A-774C-4914-9E3B-18645117428A with DE7E251E-7758-40A4-98E0-87557E9F31F0 and save. Close any open movie widget in Dashboard, then re-open it. Now it works.
