Who is more globally recognised these days?
The Hulk, or Angry Birds?
I am not sure, but I bet it would be a close race.
Personally, I am just waiting for the next Angry Birds movie crossover. They have already done Rio and Star Wars, so the scene above may not be too far away. An Angry Birds / Avengers movie tie-in could happen any day!
There is even concept art for it already (note: not actual official concept art)
