Melbourne, June 10 (ANI): Late actor Heath Ledger's family members are reportedly packing their bags to travel all the way from Australia to New York to attend the world premiere of his movie, 'The Dark Knight'.

The film, according to the Los Angeles Times, is dedicated by director Christopher Nolan to the actor who passed away this year, and would also carry a memoriam to the actor at the end.

"Word is that Heath Ledger's family will travel from Australia to attend the world premiere of The Dark Knight, the late actor's final completed film, in New York in late June," The Daily Telegraph quoted the paper, as saying.

The movie, due for a July release, will see Ledger playing a psychotic, mass murdering, skateboarding Joker. His performance has already been praised in reviews.

The actor died at the age of 28 years, after he took an accidental overdose of multiple prescription medications in his New York apartment on January 22.

In fact, many claim that it was Ledger's edgy portrayal of the Joker in the forthcoming Batman movie that had left him unbalanced.

However, 'Batman' actor Christian Bale denies this, insisting that the Perth-born actor was in a calm mood before his shocking death.

"He was incredibly intense in his performance but incredibly mellow and laid-back," said Bale, 34, in a recent interview to US magazine Details. (ANI)
