DreamWorks Animation returns to the world of dragons and Vikings in this sequel to their successful 2010 outing How to Train Your Dragon. The original film followed the exploits of a Viking chief's son, who must capture a dragon in order to mark his passage into manhood and prove his worthiness to the tribe. -- Rotten Tomatoes
The scuttlebutt around DreamWorks Animation's Glendale campus is that Number Two is a quality followup.
I think it will do better than the first installment, but I guess we'll see.
* Looking at this teaser, I was reminded that William Wellman, director of the World War I epic Wings and a lot of other classics, was the first director to understand that scenes of flight were pretty limp without clouds to give audiences a sense of speed and scale. This trailer is a good example of what Wellman figured out in 1927.
