Heath Ledger's family attended the New York premiere of 'The Dark Knight' last night (14.07.08).
The Dark Knight is the sequel to Christopher Nolan's 2005 critical hit, Batman Begins.
Batman and Gordon find alliance with a newly appointed DA Harvey Dent to stop a vicious killer with a warped sense of humor known only as The Joker, a threat to both the good, and the evil of Gotham City.
Kim Ledger - the father of Heath, who died in January from an accidental prescription drugs overdose aged 28 - and his wife, Heath's stepmother, Ines, avoided the red carpet but made their way into the cinema through a back entrance to watch Heath's performance as The Joker in the new Batman movie.
As he left the cinema, Kim gave photographers the thumbs up sign, and told reporters the film was "very good".
Heath's co-stars were also at the exclusive event, where they paid tribute to the actor.
Christian Bale, who plays The Caped Crusader for the second time, said: "Working with Heath was fantastic. He steals the movie and I'm quite happy to say that. He's a hell of a talent and created a Joker that's very iconic and one that will become a classic portrayal of the ages."
Sir Michael Caine, who plays Batman/Bruce Wayne's butler Alfred Pennyworth in 'The Dark Knight', added: "I couldn't believe the intensity and ferocity of the performance. But when we were sitting down between takes, he was completely ordinary. He wasn't preparing himself or saying 'Please leave me alone, I've got to do this.' Instead he was talking to me.
"We would sit and chat and have a cup of coffee, then suddenly they'd say, 'We're ready, Heath,' and he'd go straight into The Joker. His energy was astonishing, especially when it came from this kind of calm. He's certainly the best villain I've ever seen."
Heath's performance as The Joker - a part made famous by Jack Nicholson in 1989 movie 'Batman' - is already receiving rave reviews, and critics are tipping him for a posthumous Oscar nomination at this year's ceremony.
