Warwick's roles have taken the veteran actor from his roots in Surrey, England, to galaxies far, far away, to the magical world of J.K. Rowling's 'Hogwarts', and to C.S. Lewis's fantastical land of Narnia in a career spanning over two decades.

Warwick began his career purely by chance as a boy in 1981. His grandmother heard a radio announcement calling for people under four feet tall to appear in the new 'Star Wars' film, 'Return of the Jedi'. Warwick's gestures were so characteristic of George Lucas' vision of an Ewok, that he was recast as 'Wicket', who became one of the film's lead creature characters. After the huge success of the third 'Star Wars' epic, Lucas made two Ewok movies for ABC television,'The Ewok Adventure and 'Ewoks: Battle for Endor', with Warwick reprising his role as 'Wicket' in both projects.

Two years later, the 3ft 6' talent was called to Elstree Studios in London for a meeting with producer George Lucas and director Ron Howard about a new project called 'Willow', with the title role written specifically with the actor in mind. The project, in which he co-starred alongside Val Kilmer, allowed Warwick to showcase his acting talent beyond the portrayal of strange creatures hidden behind special makeup, earning him a Saturn Award nomination from the Academy of Science Fiction, Fantasy and Horror.

Following that big screen success, the teenage Warwick was immediately back in front of the camera, this time for the small screen, in yet another fantasy epic. He was cast in two series for the BBC -playing the swashbuckling mouse, Reepicheep, in the Narnian adventure 'Prince Caspian' and the 'Voyage of the Dawn Treader' then returning to C.S. Lewis' wondrous world as 'Glimfeather the Owl' in 'The Silver Chair'. He next followed with his first villainous role in the cult horror classic, 'Leprechaun', whose success spawned no less than five sequels over the years, with Warwick returning to the title role in each.

In 1997, he returned to filmmaker Lucas' famous galaxy far, far away in Star Wars Episode 1 The Phantom Menace,
