Late actor Heath Ledger is set to be immortalised in the form of a toy doll - with his grieving family's blessing. Ledger had recently finished playing The Joker in the forthcoming Batman film The Dark Knight when he was found dead in his New York apartment last month (22Jan08). However, only a week after the Aussie star's funeral, a range of The Joker dolls have been revealed by toy giants Mattel. The action figures are set to be marketed alongside the new movie - tipped to be this summer's (08) major blockbuster. Two versions of the Heath joker doll will hit stores in May (08) - one comes with a rocket launcher and the second is armed with a knife. A spokesman for the star's family says, "Heath was very proud of his work in the film and his family is aware and supportive of the plans for the movie." Toxicology results released earlier this month (Feb08) revealed Ledger was killed by an accidental overdose of prescribed medications.
