SIR Ian McKellen is set to return to the realm of fantasy again after signing on to play the narrator in a new star-studded film called STARDUST. The Lord Of The Rings star will add his voice to the production, which stars Michelle Pfeiffer, Robert De Niro andClaire Danes, according to trade paper The Hollywood Reporter. The film follows the adventures of a lovestruck teen who promises his sweetheart he will retrieve a fallen star by venturing into the land of the fairies. The movie, which wrapped late last year (06), was adapted from Neil Gaiman's novel of the same name. Stardust began life in 1997 as a comicbook mini-series.
