Mr. Link (Zach Galifianakis
) is 8 feet tall, weighs 630 pounds, and covered in fur. He can also talk and write letters, as he does to fearless explorer Sir Lionel Frost (Hugh Jackman
) when he grows tired of living a solitary life in the Pacific Northwest.
Frost is astounded when he meets the creature, especially when he realizes how humanlike Mr. Link is. They go on a journey to find Link's longlost relatives in the fabled valley of Shangri-La. Along with adventurer Adelina Fortnight (Zoe Saldana), the explorers encounter more than their fair share of peril as they travel to the far reaches of the world.
