Speaking of the MCU guidebook... In the guidebook about the Incredible Hulk, it states it covers the Incredible Hulk, no other media is mentioned.
However under the heading 'Stark Update', the following is revealed:
With Stark Industries out of the weapons business, the military contracted Hammer Industries to design a single-pilot attack vehicle under General Thunderbolt supervision, when it was shot down during a field test in the Congo, Iron Man was sent to rescue the pilot, but Tony was aware the military hoped to manipulate him into killing fighters in the region. He therefore deliberately avoided slaying any of the pilot's captors. Afterwards, General Ross scolded Stark for turning his back on the US military.
I've seen The Incredible Hulk a few times, but can't remember any of this. Does anyone else, or should i pay more attention to these guidebooks, as it can reveal additional info to the MCU?
