How To Train Your Dragon was a hit in 2010. But its sequel seems poised to soar to even greater heights. After a glamorous red carpet world premiere at the Cannes Film Festival on Friday, How To Train Your Dragon 2 is looking to bust out of the gates when it opens June 13. Eric Wold, a senior media analyst for the B. Riley & Co. investment firm, is feeling very bullish that Dragon 2 "should generate significantly greater revenues than the first." A big factor is that children, and adults, have come to love the original through the release, DVDs and word-of-mouth.
