Did anyone watch this? I believe it was released last year (2006) in the USA. It is a movie that poses the hypothetical question "What would happen if George W Bush was assassinated?" The movie uses archival/ news footage and advanced computer techniques to create a movie using the real life people (Dick Cheney, Donald Rumsfeld, etc.) as the actors. Apparently almost noone went to see it in the USA (where it was barely promoted - perhaps it was considered to be too controversial) but it has been successful in the international film festivals.
