Johansson, Harbour Discuss Constraints of Long-Term Roles

Scarlett Johansson, who played Black Widow, felt that some of the Marvel movies weren't interesting for her character because the cast was huge and there was a lot going on.

She also felt like it was limiting because she couldn't do things like change her hair.

David Harbour from 'Stranger Things' understands this, as he feels the same after a decade on the show and wants to try new roles.
