The new film was made in New Zealand and scenes were shot at different locations around the country, including Tapanui in West Otago and Redwoods Forest in Rotorua.
This brought some of the film's biggest Hollywood stars to small town New Zealand.
Acting legend Robert Redford was in New Zealand for filming, as was Bryce Dallas Howard (daughter of acclaimed director Ron Howard), Wes Bentley (American Beauty, The Hunger Games), Karl Urban (Shortland Street, Star Trek, Dredd) and child star Oakes Fegley (Boardwalk Empire).
The film crew also spent some time in Wellington at Stone Street Studios in Miramar.
Meanwhile, Wellington's Weta Digital was responsible for the computer-generated dragon.
Entertainment Weekly said the Kiwi animators watched "hours upon hours of funny animal videos online" to capture Elliot's movements.
"There's one video of a giant panda tumbling in his cave, and we looked at that again and again as our Elliot - this big animal who just doesn't know what to do with his body," Healy told the magazine.
The movie is due to be released in August this year.
