Hulk (2003)

A character that has been pillar of Marvel Comics since it debut in 1962, The Incredible Hulk and his alter ego Bruce Banner has been synonymous with the culture of superheroes and of comic books. Being just one of the many creation of Stan Lee & Jack Kirby, the Hulk's arc has remained generally the same, The battle to control his dangerous alter ego with varying success over the near 60 years of its inception. A lonely isolated character, who inadvertently became a matriarch of a family of hulk like characters, and a founding members of the Avengers. Has found short-lived peace by separating the man from the beast, from coming to terms and controlling the hulk as a complete entity, and at one point actually dying and laid to rest for a number of years, just to be resurrected for nefarious gain.

Hulk (2003)  is based on the backstory of the comic book history of Bruce Banner and the story of his abusive father, as Bruce would eventually grow up to be a shy but brilliant scientist. An accidental exposure to an extremely high levels of gamma radiation has acted as a catalyst to form and create the Hulk, but the source of the rage that fuels the Hulk has come from traumatic childhood experiences. The comic book did a deep dive that resulted in a truce at a point when Banner had a coming of terms and symbiotic relationship with his alter ego. Director Ang Lee took that construct and made a movie about the broken relationships of a child and their parent, With Bruce and his father David, with Betty Ross and her father General Thaddeus Ross.

The major difference was that Bruce was born with the Hulk already inside him as a result of passed  on genetics of mad scientist father David Banner.  The movie introduced Hulk like dogs, a concept designed by Ang Lee's son.  In the comic books the Ross's would eventually become gamma infused with father and daughter becoming Red Hulks, Bruce's cousin Jennifer becoming a green She-Hulk from a blood transfusion, and Rick Jones becoming a character known as A-Bomb from his latent exposer to gamma radiation, all of whom have become surrogate family to the original green goliath.
