A new extended trailer for Avengers 2: Age of Ultron has debuted, with more Hulk-busting action and a longer glimpse of Korean actress Kim Soo-hyun (see "Marvel Movie Round-Up").
 
For course, Ultron has some more to say, and Hawkeye, Quicksilver and Scarlet Witch all have another second or so each.  No hint of Heimdall or Loki yet (see "Elba, Hiddleston in 'Age of Ultron'") but it’s only the second trailer.  The first trailer can be seen here: see "Another Minute of 'Age of Ultron'."
