It's been more than a year since the most respected performer of Batman's The Joker, Heath Ledger, passed away. Gone but certainly not forgotten - although Ledger died before the movie was released, his hard work was duly recognised - his performance in The Dark Knight won the Best Supporting Actor award at the Oscars and Golden Globes. This fantastic film really needs to be seen at an Imax cinema to fully appreciate its brilliance. As it's not likely to be shown again, or at least for a while, after the second round of screenings in January, the next best solution is to get the DVD or Blu-Ray and find a friend with an absolutely massive TV. The film is directed by Christopher Nolan, who was also responsible for the first movie in the series, Batman Begins. Christian Bale reprises his role as Bruce Wayne/ Batman to fight for justice alongside Commissioner Gordon (Gary Oldman), district attorney Harvey Dent (Aaron Eckhart) and Dent's assistant Rachel Dawes (Maggie Gyllenhaal). Their main enemy is Ledger's dark, enigmatic Joker who seems intent on destroying law and order in Gotham City. It's hard to describe much more of the plot without ruining the movie, but Ledger's stunning performance and the film's astonishing visual effects make this absolutely crucial viewing.
