There are many differences between the film and comic book properties, the primary differences between the two are documented here. In the comics, Ho Yinsen--the man who helped Tony build the first Iron Man suit--was Chinese. The film's Yinsen (Shaun Toub) is Afghani, from the fictional town of Gulmira. However, Yinsen is a Chinese name and it would be unlikely for an Afghan to be so named. Obadiah Stane, in the comics, was a rival businessman, and had his own company, Stane International. However, like his film incarnation, he was friendly with Tony's father before his passing. The group that kidnaps Tony Stark is implied to be connected to the Mandarin, Iron Man's archenemy. The Mandarin had nothing to do with his kidnapping in the comics (well, not directly, anyway). The Ten Rings are also involved with Obadiah Stane, who personally ordered the hit on Tony Stark. This is not the case in the comic book series. Jim Rhodes was a full-bird Colonel in the United States Marine Corps when he first appeared in the comics, while in the film he is a Lt. Colonel in the Air Force. JARVIS, the A.I. featured in the film, is a flesh and blood butler in the comic books.
