Introduction:

A montage during the opening credit sequence details the film’s backstory and the origin of the Hulk. General Thaddeus “Thunderbolt” Ross (William Hurt) meets with Dr. Bruce Banner (Edward Norton), the colleague and lover of his daughter Betty (Liv Tyler). He wants him to revive a World War II-era military bio-force project, but tells Banner the goal of the experiment is to make human beings immune to gamma radiation. The experiment fails, transforming Banner into the monstrous Hulk (voiced by Lou Ferrigno), and injuring Betty. Now a fugitive from the United States Army, Banner has been on the run for five years.

As the film opens, Banner works at a soda bottling factory in Rocinha while searching for a cure for his condition (through analyzing the properties of certain rare, Amazonian plants and herbs) with the help of a colleague on the Internet, known only as “Mr. Blue”. He is also learning meditative breathing techniques from a martial arts expert (Rickson Gracie) to help regulate his pulse rate and keep his anger under control, and has not transformed in 158 days. After Banner cuts his finger, a drop of his blood ends up in one of the bottles, and is eventually ingested by an ill-fated consumer (Stan Lee) in Milwaukee, Wisconsin. This accident points Ross to Banner’s location and he sends a team, led by Russian-born British special ops expert Emil Blonsky (Tim Roth), to capture him. Banner escapes Blonsky by transforming into the Hulk and fighting off his team inside the bottle factory. After Ross explains how Banner first became the Hulk, a vengeful Blonsky agrees to be injected with a new super soldier serum, which gives him enhanced speed, agility, reflexes, endurance and healing.
