While the concepts behind most of Albert Brooks' films don't always hold up over the course of an entire movie, they are almost always interesting. One can tell that Brooks attempts to give his audience food for thought, along with laughs. His latest is called Looking for Comedy in the Muslim World.
Here is IMDb's plot outline: "To improve their relations with Muslim countries, The U.S. Government assigns comedian Albert Brooks to find out what makes the Muslim people laugh."
