Movie bosses believe the flick may contain material that children find "confusing and upsetting". The movie starts where Lewis Carroll's book ended. Australian Mia Wasikowska steps into shoes of Alice, who is 19 when she returns to Wonderland.
Alice is finding it difficult to fit into Victorian society. She escapes from a garden party minutes before a marriage proposal. When she sees the White Rabbit, she goes down a hole and ends up in Wonderland.
Among her many adventures the teen battles a dragon, who is under the spell of the Red Queen, played by Helena Bonham Carter. The movie stars Johnny Depp in the role of the Mad Hatter. The film will hit cinemas Down Under on Thursday.
