Fans and film critics alike were already getting ultra excited about the release of the new Batman movie The Dark Knight, but then something happened to add a new element to the film.

Heath Ledger is starring in the film as The Joker, and his untimely death last month added a spooky edge to proceedings.

We’ve already seen the high resolution trailer for the film, as well as the brilliant Lego version, which I think I secretly prefer, and now we have a sneek peek, and behind the scenes interviews.

We get to hear from Christian Bale, who describes Ledger’s performance as The Joker as the ultimate bad guy. High praise indeed. The film is due out on 18th July.
