Any manga fan worth their salt has been anxiously waiting for (or cautiously optimistic regarding) any news regarding the upcoming 3-D, CGI adaptation of "Astro Boy" -- based on the classic manga by the legendary Osamu Tezuka. And while the addition of major Hollywood stars (as well as a "Little Brit") lending their voices for the film have been dominating the blogs regarding the upcoming film, little has been seen in regards to teasers or promo stills...until now.
The fine folks over at Cinematical got the jump today on the first look at "Astro Boy," with an exclusive sneak peek at a new publicity still AND a 30-second teaser trailer that -- coming from an "Astro Boy" fan -- is absolutely jaw-dropping. The trailers up above, now check out the promo art after the jump.

Set to hit theaters in October 2009, "Astro Boy" stars the voices of Kristen Bell, Nicolas Cage, Donald Sutherland, Nathan Lane, Eugene Levy, Matt Lucas and Freddy Highmore as the title character. The story centers around Astro Boy, a young robot with incredible powers. During a quest to not only learn the extent of his powers by taking on giant robots and monsters, Astro Boy soon learns that his adopted relatives and loved ones as well as his home, Metro City, are in grave danger, and it's up to him to save the day.
