"Clearly, there's a purpose to us putting him in the end of that movie. We do have plans for him. I wouldn't say we ever feel the need to rush anything one way or the other. We succeeded in Phase One because we stuck to our guns and stuck to the plan. That plan took place over many, many years and it ultimately paid off. I see Phase Two unfolding in the same way of us taking our time, us doing what's right for each individual movie, while folding in elements that will not only build up to the culmination of Phase Two, but even Phase Three."
The producer wouldn't reveal specifically if Thanos is appearing in Guardians of the Galaxy or The Avengers 2. However, he did say they will probably recast the role, played briefly by Damion Poitier in the end-credit scene.
"I think we feel pretty free to recast. That was cast for literally that one shot. Depending on what the role requires from future movies, we'll go from there."
Kevin Feige also revealed how pleased he was that Thanos' reveal led to new fans delving deeper into the Marvel comic book world for more information on the character.
"Suddenly, you have a million people who had never heard of an Infinity Gauntlet or a Mad Titan learning those terms. I love that. I love when the experience goes beyond the movie theater and encourages people to look deeper into our universe. I was equally excited by the notion that people went out and tried shawarma for the first time."
