I realize that's obviously correct, and that Marvel Studios as it exists now - and the overall MCU - wasn't even remotely in effect in 2003, but shouldn't the Eric Bana Hulk technically be considered the first movie in the MCU? If only because The Incredible Hulk is basically a direct sequel, just starring a different cast?
At the end of Hulk, Banner is in hiding in South America, and then at the beginning of The Incredible Hulk, Banner is still in hiding in South America, only to come back to the states and the same, basic dynamic he left in Hulk. Again, I know The Incredible Hulk was basically a soft-reboot, but it was meant to be a soft-sequel to Hulk as well, just with a different cast. And because South America links Hulk and The Incredible Hulk, and because William Hurt's General Ross (along with Tony Stark in a TIH post credit scene) links to Civil War, at least when it comes to organizing my Blu-rays, I might just throw in Hulk with the rest of them...
