There is already a movie about ramen. It's called Tampopo, which isn't just one of the best food movies, but in my opinion, one of the greatest films of all time.
Now there's a documentary called Jiro Dreams of Sushi where the central subject is Japan's other ubiquitous dish: sushi. It tells the story of 85-year old Jiro Ono, the first sushi chef to earn three Michelin stars and a purported Japanese national treasure, who is a raw fish perfectionist–the Japanese Ferran Adria, it seems.
I've actually heard about the movie for quite a while now, but Magnolia Pictures has released a more complete trailer on YouTube and Apple's Trailer page, and it makes me salivate at the hard core sushi food porn and loving SteadiCam shots more than any footage I've seen before.
Unfortunately, this latest amuse bouche is the only taste we get of the movie until it officially opens in March.
