Yesterday, we brought you an update from Don Cheadle about his experiences in the War Machine armor during "Iron Man 2," but today we a few more, exclusive details to share about the much-anticipated debut of the armor Tony Stark isn't wearing in the film (as far as we know).

When "Iron Man 2" actor Sam Rockwell dropped by Splash Page HQ recently, we asked him about the relationship between his character (rival industrialist Justin Hammer) and Don Cheadle's character (Stark's military buddy James "Rhodey" Rhodes). After all, they seemed pretty chummy in the "Iron Man 2" trailer that premiered during Comic-Con in San Diego this year.

"Don and I, we're working together," said Rockwell of the pair's relationship. "He works with me in spite of some of my personality flaws." Read more...

Playing a superhero is never easy—especially when somebody else has played the role first. Such was the dilemma for actor Don Cheadle, who takes over the role of James "Rhodey" Rhodes from Terrence Howard in next summer's "Iron Man 2." In addition to replacing Howard, Cheadle also gets to don the War Machine armor, something that Howard was never able to achieve.

In an interview with Moviefone, Cheadle admitted to some awkwardness surrounding the takeover due to his friendship with Howard—but the discomfort didn't last too long.

"Terrence is a friend of mine," said Cheadle. "But the actual playing it, I just felt like it was my role. I wasn't made to feel like I had to sort of take care of what was done before. I really feel like I could make it my own." Read more...

When it comes to movies, a well-received first outing almost always calls for an even better follow-up, and in the case of the in-development "Iron Man" franchise, fandom has set its collective expectations high. But while Don Cheadle acknowledges fan excitement, the "Iron Man 2" star explained that the mindset behind the sequel is primarily rooted in expanding on what worked in the first film.

When asked about the general conversation that took place with director Jon Favreau on the "Iron Man 2" set, Cheadle explained that his motivation wasn't necessarily to make a bigger film, but a film that explored the ideas set during the first installment in a big way.

"You know, [topping the last film] wasn't really ever the discussion," Cheadle told MTV News, "We never said, 'How do we beat it?' in my opinion. We just said, 'How do we take what happened in the first film and pay it off now in the second film and really explore what it means now for a character to be going around as an actual super hero that everybody knows.'"

The wait is over for one of the most eagerly anticipated moments at this year's Comic-Con, and fans' patience was rewarded during Saturday's "Iron Man 2" panel.

Along with bringing along most of the film's lead actors, director Jon Favreau was accompanied by a surprise guest at the panel: War Machine. The counterpart to the Iron Man armor was revealed at the end of a montage that offered new footage of Tony Stark (Robert Downey Jr.) and Nick Fury (Samuel L. Jackson), Whiplash (Mickey Rourke), Justin Hammer (Sam Rockwell), Black Widow (Scarlett Johansson), and James Rhodes (Don Cheadle). Oh, and War Machine, too

"We wanted to use Comic-Con as our venue to have the first images of War Machine come out," Favreau told MTV News. "There's been talk of whether it was [in the film] or not, and we've been holding back. We haven't talked officially about it. We wanted to show the fans some of that." Read more...

Those of us hunting for "Iron Man 2" news have had to settle for mysterious set photos and unverified concept sketches lately, but a pair of big updates finally hit the 'Net today, courtesy of a recent interview with the Marvel blockbuster's cast and director Jon Favreau.

"Rhodesy is definitely stepping up in this film. Let me put it this way: Tony's not the only person with technology in the film," Favreau told Empire when asked about the likelihood that Don Cheadle will suit up in the War Machine armor. Read more...

We may never know what ultimately led to the Don Cheadle/Terrence Howard switch on "Iron Man 2," and if Robert Downey Jr. knows, well, he isn't talking (at least to us).

But one reason it definitely did NOT happen is because the character of Jim "Rhodey" Rhodes was scaled back for the sequel, "Iron Man 2” screenwriter Justin Theroux told MTV News.

"I can't really speak to the plot stuff and all the rest of it but Rhodes is completely present in a very strong and big way," Theroux said of the man who would be War Machine. "He's COMPLETELY present." Read more...

"Iron Man" director Jon Favreau had plenty to say about the film future of Marvel's armored hero during a live, online Q&A session with fans, including some hints about the storylines that will drive "Iron Man 2," the characters -- both good and bad -- that could make an appearance, and how he feels about the other big superhero movie that hit theaters this year.

"Mandarin is still an important figure in the Iron Man universe," wrote Favreau during the live chat hosted by the LA Times' Hero Complex blog. "We have an interesting take on him that allows us to incorporate the whole pantheon of villains. The whole 10 Rings thing in ['Iron Man'] was a good tease for it."

Later in the chat, when asked by a fan if there was any thought given to introducing a female villain such as Madame Masque, Favreau seemed to spark what's likely to be the next big "Iron Man" rumor, responding, "Female villain... Now there's an interesting notion." Read more...

During a recent discussion of the past, present and future of the "Iron Man" film franchise, writer/director Jon Favreau name-checked Marvel's "Invincible Iron Man" series as a print element that both draws from and leads into the character's live-action adventures.
