Avengers: Age Of Ultron - 25 Moments From The New Trailer You Need To See

6. Tender Hulk

In the first trailer, Hulk's hand was seen tenderly touching Natasha Romanoff's which suggested two things; first, that Bruce Banner was fully in control of the Hulk and could think clearly whilst in his big green form and, second, that there was a potential romance between he and Romanoff. This trailer showed the Hulk's concerned face during the pair's moment and it certainly looks as though he is concerned about the female hero.
