Nausus was never mentioned in the 2008 Walden/Disney movie of "Prince Caspian", but was included in the 2010 Walden/Fox movie of "The Voyage of the Dawn Treader", as one of two Fauns aboard the Dawn Treader.
He was played by Australian actor, Steven Rooke.
Nausus was chosen to be part of the crew of the Dawn Treader, in the service of King Caspian X, in 2306.
He was on deck at the time when Edmund, Lucy and Eustace first arrived on the ship. He also took part in the Battle of Narrowhaven, fighting with a halberd, and knocking out a slave-trader with an impressive aerobatic display.
He was last seen on board the ship when they last encountered the Green Mist, when it manifested itself as a giant Sea Serpent, getting ready to attack them. He had been gazing up in fear at it, while drawing his sword, which obviously he must have been trained in using.
- In one deleted scene, in the VDT film, Nausus brought Eustace some soup when he was feeling seasick. Eustace was delirious, and thought Nausus was his mother, and then asked Lucy, "Why does mother smell like a goat?", greatly insulting Nausus.
