Question: In this version of the character, why is he named David Banner instead of Bruce Banner?
Question: Given how long it ran and its popularity, was there ever talk of a crossover with Dynasty regardless of different networks?
Answer: No, back then such things were unheard of. Too much politics, contract disputes and what would the characters do if they met.
Chosen answer: Bruce has always been the character's middle name. In the comics he is Robert Bruce Banner, here he is David Bruce Banner. Apparently the executives behind the show preferred the name David.
