It seems that the Captain America sequel is having late re-shoots, which are fairly common for big blockbusters and are more often that not, nothing to worry about. The internet does have a tendency to blow these things out of proportion however.
As Celebitchy mentions:
People are starting to wonder if there is trouble on the set. Perhaps Chris Evans isn’t so easy to work with (as he's mentioned in a previous interview). Now rumors (and these are only rumors) suggest that Chris’ Cap character is set to be killed off in either Cap 2 or Avengers: Age of Ultron. Maybe this is only publicity to suggest that the Captain America: The Winter Soldier will take up the Cap shield. Or maybe is really a goner for Marvel.
Evans has said himself in the aforementioned interview with Celebitchy that his intentions are to work on more independent films rather than following in the footsteps of ; who has paved the way as one of Marvel's most prominent leading men.
The goal was to get to a point in your career where you can make the movies that you want to make, do what you want to do, and have access and freedom.
Well that seems pretty reasonable to me and whilst there may not be any truth in this current speculation, it seems like we may see assume a role of more modest proportions in the not-too distant future. What are your thoughts?
