One of Finland's biggest newspapers mentioned SHH!

Translated from Finnish newspapers netsite;
"What will happen to Heath Ledger's Batman movie?"
Actor
Heath Ledger's tragic death gives headache to the producers of his last movie.
Fans all over the world are wondering, if Ledger really got his scenes/dubbing done in The Dark Knight movie.
Action movie "The Dark Knight" is suppoused to come to theaters next summer. In the movie, Ledger plays Batman's arch nemesis The Joker, and he had filmed all of his scenes last year, months before he died.
But there are lots of insecurence on the air, did Ledger do all the stuff they need for the film after filming it (Looping/Dubbing).
Especially in big movieprojects actors record their lines after they are done with the filming, cause of the possible noices or other factors in the background. "Looping" like this can't happen in the Ledger's case ofcourse.
According to E! Online -website Ledger "didn't do any dubbing/looping", but the actor himself said while promoting his movie
I'm Not There that he was done with The Dark Knight. Also many fansites, like
Batman-on-Film.com ja
Superherohype.com have supported this information.
Movie's director
Christoper Nolan and the workteam Warner Bros. have been silent about the destiny of The Dark Knight.
If it is so that, there's no dubbing done by Ledger, the studio has two choices: They have to hire someone to imitate Ledger's voice or combine the lines from Ledger's earlier scene's word by word.
The movie has been marketed restrained, because of Ledger's death. One of the pruned ads is a poster, where Ledger smiles in his frightening Joker make up and asks to the camera; "Why so serious?"
Sorry if the translation job is terrible, I tried my best.
EDIT:
Seems like some of the people from the magazine actually visit SHH forums, cause I remember that some of the stuff has been said by the users.
