7) Guillermo del Toro’s The Hulk
Speaking of The Incredible Hulk, that series remains so definitive a take on the character that there has never been another live-action series starring him. That could have changed, though, if an early idea from the MCU’s television arm had gone to plan.
When made head of Marvel Television, Jeph Loeb pressed ahead for a new TV series starring the Jade Giant. He even got acclaimed fantasy/horror director Guillermo del Toro in as showrunner. Not much is known about what del Toro’s take on the character would have been, but it was announced that Red Hulk was to be the main villain.
Fans were raring to go with the series but, like a lot of projects del Toro gets attached to (seriously, the guy must be cursed or something), it never came to fruition. Loeb instead moved forward with another idea, one that would develop into Agents of S.H.I.E.L.D. – and the rest is history.
