That he is willing to play Thor forever!
But isn't sure everyone will want that and thinks they may be tired of him playing the role!
So if it's up to him...he'll be playing Thor forever.
Which is okay by me so long as the script is right.
That or just make an ongoing Thor series not a mini series but an ongoing one like Hercules the legendary Journeys!
Hell I'm sure Taika would Direct that and most the cast would be up for it.
I would absolutely love a series where he goes and rights wrongs in the 9 worlds!
...He just said in his recent interviews that this will probably be his last, and he feels like Marvel wants to replace him
