RDJ can still do other stuff--he just doesn't, because he makes zillions being in Disney movies.

Same for Daniel Craig and Chris Pratt and any number of actors.

Daniel Craig /killed/ it in Knives Out. And in Logan Lucky (with Adam Driver, who also does great independent and arthouse films).

Disney may dominate theaters and box office scores at the end of the year, but that doesn't mean great independent and artistic films aren't being made (or that Disney movies can't be art).
