There have been numerous rumors floating around the Internet regarding the Iron Man sequel. Below, we've summarized a series of possible spoilers for the movie:

• Jon Favreau planned Iron Man as the first in a trilogy.

• According to MTV Movie Blogs, Favreau believes the sequel will explore darker story elements, such as alcoholism, which he intentionally set aside from the first film.

• Wikipedia quotes Robert Downey Jr. as saying: "The next one is about what do you do with the rest of your life once you've completely changed. I think the drinking and all that stuff would be a good way to confront his age, to confront his doubts, to confront the fact that maybe Pepper gets a boyfriend."

• Terrence Howard has said his character would become War Machine in the sequel, just like in the comics: "Judging from how that audience responded, we got a pretty good shot of having some War Machine go down."
