Two new featurettes for director Ang Lee’s ambitious adaptation of Life of Pi have been released, Collider said.

Lee has stated many times that this is the hardest film he’s ever had to make, and it’s obvious that’s not an understatement when you realize that the premise involves a young boy and a tiger lost at sea for the majority of the film, accoridng to Collider.

The featurettes focus on the meticulousness that went into creating the CG tiger Richard Parker, and choosing to shoot the film in 3D. The latter featurette includes 3D guru James Cameron talking about Lee’s use of 3D in the pic and how it enhances the story.
