The Marvel Cinematic Universe has been going through a rocky patch in the last few years, and many believe that its best days are behind it. This in part is due to the loss of several major characters fans invested 10 years of their lives in, such as Robert Downey Jr.’s Iron Man, Chris Evans’ Captain America and Scarlett Johansson’s Black Widow. However, one original Avenger who has long been rumored to be due another shot at a solo movie is the Hulk, but actor Mark Ruffalo has apparently been told he cannot talk about that.
