Long-time Marvel producer Feige suggested that Thanos, who was confirmed to appear in The Avengers 2 and Guardians of the Galaxy earlier this week, was featured at the end of The Avengers for a reason.
"There's a great track record now about lobbing something in at the last moment to get the audience buzzing," , Feige told Collider.
"Particularly when it came to Thanos, [we knew] that most people in that audience had no idea who that purple guy was - but they could clearly tell he was important, and knew if they asked the two or three people sitting next to them, somebody would know who he was.
"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."
Feige also told MTV News that actor Damion Poitier, who played Thanos briefly in The Avengers, is unlikely to reprise the role.
"I think we feel pretty free to recast. That was cast for literally that one shot. Depending on what role requires from future movies, we'll go from there," he said.
