The unveiling is timed to the Blu-ray release and the 30th anniversary of Steven Spielberg's classic film "E.T. the Extra-Terrestrial."
All six figures are being worked on simultaneously by a huge creative team at Merlin Studios in West London, using reference photographs and footage from the film to capture a perfect likeness.
The statues will be unveiled in London, Amsterdam, Berlin, Sydney and Hollywood Oct. 22 and in Tokyo in March.
"We are delighted to be welcoming one of the greatest movie characters of all time to the attraction," Nicky Marsh, Madame Tussauds global marketing director, said in a statement Friday.
"We are honored that Madame Tussauds has chosen to mark this historic occasion in a way that only it can do," said Craig Kornblau, president of Universal Studios Home Entertainment. "In celebration of this beloved film's 30th anniversary, legions of 'E.T. the Extra-Terrestrial' fans will have the opportunity to relive film history, both through the film's historic Blu-ray debut and at Madame Tussauds museums in Hollywood and around the world."
