NarniaWeb member icarus found an entry on Lee Ravitz’s resume, stating that he was involved in green screen tests for the Dufflepuds in The Voyage of the Dawn Treader. This leads us to believe that the Dufflepuds with either be entirely CG, or they’ll be motion captured much in the way that Gollum was motion captured for The Lord of the Rings. Lee Ravitz’s resume states:
Role: Dufflepud (Green Screen VFX Test Shots Only)
Type: Film (Feature)
Production: Voyage of the Dawn Treader
Director: Angus Bickerton
Company: Purple Sail Ltd.
Venue: Twickenham Studios
