One of the early releases of MCU that helped it gain a strong foothold in Hollywood was 2008’s The Incredible Hulk. Actor Edward Norton played the role of the accidental superhero with aplomb. While the movie grossed a moderate worldwide sale of about $265 million, it managed to establish the green monster as one of the initial Avengers.Four years later, when the first ensemble of the Avengers came forward in the movie The Avengers, viewers were surprised to see Mark Ruffalo playing the Hulk. Since then Ruffalo has been the actor behind the Hulk. However, Norton's Hulk has left a mark in the minds of fans who are left wondering why he left the MCU.Marvel head Kevin Feige had stated that they needed an actor who could be a team player with other actors in the ensemble. However, Edward’s agents denied these allegations leading to a lot of speculation. With Liv Tyler’s Betty Ross slated for a comeback in Captain America: New World Order, it is time for fans to wonder whether Norton’s Hulk may return to MCU.

It’s the MCU movie that feels the least like an MCU movie, probably due to Ruffalo replacing Norton and the Hulk redesign in the Avengers. It’s decent fun and I like that they get the origin out of the way in the opening credits.The Incredible Hulk - Not as dull as I remember.

Mark Ruffalo was connected to serious character roles and had not done any significant lead roles till then. Except for Norton, other Phase 1 actors such as Robert Downey Jr. or Chris Evans did not have the famous tag to them. As such, Marvel Studios was relying on Norton to establish the brand.Ruffalo admits that he has not had the opportunity to play the Hulk in a solo movie as yet. However, it is undeniable that fans of the successive phases of MCU will remember Mark Ruffalo as the green monster superhero. While Edward brought focus on Bruce Banner’s personal trauma, Mark’s Bruce Banner is an endearing, bumbling, and bashful superhero afraid of his own powers but eager to help.
