Reports that Captain Marvel has been cast and will appear in some form during Age of Ultron. Lot of opportunities to introduce Carol. I thought they have missed opportunities at teasing her during the Avengers and Winter Soldier as a pilot of a fighter jet which could have been perfect to hear referencing her role in those films. The standout cases being shooting at the Hulk or Cap in the respective films.
The parts where we see the behind the scenes of filming The Hulk is what I like to see. They're actually filming on location with real sets, and then CGIing the Hulk in post. It's great but also sad that this is now considered impressive for film makers.
