After holding its Hollywood premiere a few weeks ago, "Oz: The Great and Powerful" brought its cast and crew to UK for a London premiere. Main cast members James Franco, Mila Kunis, Michelle Williams and Rachel Weisz were all on hand to support the special screening at the Empire Leicester Square on Thursday, February 28, AceShowbiz said.

They were joined by co-star Zach Braff and director Sam Raimi. Other celebrity guests that night included The Saturdays' Una Healy, model Danielle Lloyd and former "The X Factor" contestant Jade Ellis.

Almost at the same time the film threw its UK premiere, the final trailer for "Oz" made its way out online. It shows Franco's Oscar Diggs leading a battle to win back the throne of the Emerald City for the forces of good after being hurled away from dusty Kansas to the vibrant Land of Oz.

The small-time circus magician is believed to be the great wizard everyone's been expecting on the land, but three witches, Theodora (Kunis), Evanora and Glinda are not convinced he is. Reluctantly drawn into the epic problems facing the Land of Oz and its inhabitants, Oscar must find out who is good and who is evil before it is too late.

The adventure-fantasy movie will open wide in U.S. theaters on March 8.
