First played by Edward Norton in 2008’s The Incredible Hulk, the role of the furiously strong Bruce Banner was given to Mark Ruffalo. After the release of The Avengers in 2012, Ruffalo and Hulk became one. And because the character gained complexity and the public reacted well to his backstory, it was further developed as did his look. The lack of a standalone Hulk film allowed the character to play a more prominent role in other films of the saga such as Avengers: Endgame.
