Early on, the most entertaining scene is when Omer, a Middle Eastern terrorist living with extended family in the States, sings like a theater school dandy on his cousin' basement stage. When the American Dreamz scouts come looking for his relative who had sent in an audition tape, they find the clueless Omer instead, a perfect fit for the show' desired "Arab type." So he, with Sally and a slew of other starry-eyed future cruise boat singers (don't forget the Orthodox Jew), are chosen to compete in the calculated contest.
Hugh Grant' character, Martin Tweed, is the British producer and host of the program. Weitz deftly paints him a self-loathing celebrity, aware of the monster he' created-probably pretty close to Tweed' real-life counterpart, Simon Cowell. The story comes together when Tweed negotiates a PR deal with the President' advisors to have the head of state judge the final episode of the season. At this point, our pessimistic leader comes out of hiding and seeks any exposure he can get.
The stunt catches the attention of Omer' tent-dwelling jihad buddies back in Afghanistan, and a goofy trio of terrorists approaches Omer with a plan to assassinate the Commander in Chief. Of course the scheme' success is banking on their comrades' ability to make it to the final round with his foppish dance moves and outfits.
