>>213651200Ruffalo has the cushiest role in all of this.
The Hulk character is still technically owned by Universal but they are fine loaning him out to marvel as long as he isnt the main character in a movie.
So Mark gets to show up on set for a week, record his lines over a weekend, and collect the check afterwards knowing full well Marvel wont dare make an Avengers movie without the Hulk. Hes always going to be a part of their biggest movies and doesnt have to actually be in a lead role or say/do much of anything
