Trivia: Executive Producer Kenneth Johnson wanted to have the Hulk's skin color be red instead of green. His explanation was that red represented anger and green represented jealousy. When telling Stan Lee, creator of The Incredible Hulk about this, Stan Lee said that the Hulk's skin color was green and had to stay green.

Question: What did David's mother die from?





Answer: An illness, although it's never stated what kind of illness. David blames his dad for her death because his father never took her to the hospital. So in all likelihood, her illness was never diagnosed anyways and David might not even have known what it was.
