Whedon On Thanos & The Avengers

While chatting with Desde Hollywood writer/director Joss Whedon indicates that despite the seeing him during the end credits of "The Avengers," Thanos will NOT be the villain for "The Avengers 2".

He says: "Thanos is more powerful. He is so powerful; he is not someone you can just trot out and punch him. Like he did in the comics, you want him threading through the universe and to save the big finale for the big finale. He is definitely a part of what I have got going on. The thing about The Avengers is that they are very powerful but not very stable. So, there will definitely be some people that will shake them up in the next installment."

This suggests that we might not see Thanos and his full plan until we get to "The Avengers 3" in 2018.
