The first Hulk movie was directed by the Chinese director Ang Lee, which was really surprising. However, Ang Lee was a very famous Chinese film director who had directed many well-received films such as Crouching Tiger, Hidden Dragon and Brokeback Mountain.
The Hulk, as part of the Marvel Cinematic Universe, released a movie of the same name directed by Ang Lee in 2019. During the production of the movie, there were some conflicts between the Marvel Cinematic Universe and Ang Lee, but in the end, Ang Lee accepted the project and became the director of the Hulk.
Director Ang Lee's performance in the first Hulk was also highly praised by the people. Through the Hulk, he portrayed an image full of vitality and strength, and at the same time, let the audience feel the humor and warmth of the movie. Therefore, the success of the first Hulk movie made Ang Lee one of the high-profile directors in the Chinese film industry.

In a fanfiction scenario, the Hulk might be a result of a secret experiment by the League of Villains to create an ultimate weapon.
