The Simpsons Movie, which has been 18 years in the making, is finally due to hit theaters July 27. The movie is creating quite a frenzy around the country -- with a dozen 7-Elevens in cities from New York to California turning into Kwik-E-Marts. They are also selling Simpsons branded products in all 7-Eleven stores (I bought a box of KrustyO's). The frenzy is even bigger in Springfield, Vermont, which was chosen to host the premier of the movie.

The biggest beneficiary of the movie will be the same company that has benefited from the long, successful run of the show -- News Corporation (NYSE: NWS). After 20 years on the small screen, making News Corp's Fox billions, the big screen version will look to take No. 1 at the box office. It shouldn't have any trouble, as most of this summer's blockbusters have already come and gone, and the other new movies out that week -- I Know Who Killed Me and No Reservations -- don't have anywhere near the hype, universal appeal or the marketing push of the Simpsons.

Other beneficiaries are the aforementioned 7-Eleven, which is owned by Seven-Eleven Japan Co, the privately-owned toy company McFarlane toys, which is making The Simpsons Movie toys, and Electronic Arts Inc (NADSAQ: ERTS), which is releasing a new Simpsons video game to coincide with the release of The Simpsons Movie on DVD.
