Trivia: The filmmakers decided to make the production environmentally-friendly, using hybrid vehicles on set, zero-or-low VOC paint and locally-sourced yellow pine to build the sets, among other measures. As such, it became the first blockbuster film to receive the Environmental Media Association's Green Seal, which is displayed during the end credits.
Trivia: When Gnl. Ross is in the cooling cell to get the super soldier stuff for Blonsky, on the lid of that specific container, it says, "Developed by: Dr. Reinstein." This is the alias of Dr. Erskine, who made Captain America.
Trivia: Bruce Banner is inexplicably called Bob for several issues of The Hulk comic books. This was a mistake on the part of Stan Lee who had a hard time remembering his characters names, presumably because he drew several superhero comic book series at the same time. It was later revealed that Bruce Banner's full name is Robert Bruce Banner.
Trivia: Early drafts of the script were indeed written to be a direct sequel to the prior 2003 Ang Lee "Hulk" film. (Which explains some of the connections the films share, such as "Hulk" ending in South America and "The Incredible Hulk" opening there.) It was then retooled throughout pre-production to fit better into Marvel's Cinematic Universe concept, with producer Gale Anne Hurd referring to it as a "requel" - a combination of reboot and sequel. Finally, it was decided that the film would be a total reboot.
Trivia: Amadeus Cho is the man Bruce Banner bribes with pizza to gain access to the lab. That character is one of the new Hulks in the comics, and is played by Martin Starr, who also appeared in Spider-Man: Homecoming.
Trivia: The Hulk only says six words in the entire film.
Trivia: "The Incredible Hulk" is one of only two MCU films to not have any mid or post-credits scenes. The other film is "Avengers: Endgame."
Answer: Yes. In the alternate opening, after Bruce turns into the Hulk and causes the ice to collapse, a huge chunk of ice is broken free from the ground. In this ice is a figure dressed in blue holding a round shield with circular red and white stripes. The best way to see this is waiting until the huge ice wall breaks and then slowly advance frame-by-frame and eventually Captain America and his shield will be seen.
