Why I'm Here: Dark Knight

Back in the '50s, and then again in the '70s, when the movie industry was suffering at the hands of television or simply in a creative doldrums, there was an explosion of new formats and gimmicks - VistaVision and CinemaScope, Technirama and Cinerama, 3-D and Sensurround. For some reason - which might be obvious - we're seeing that again, with the sudden viability of IMAX theatres and the return of 3-D. I couldn't help but think of this as I sat down in the The Bridge IMAX Theatre at the Howard Hughes Center to watch a screening of The Dark Knight.

At first, it looked like Chrisopher Nolan's sequel to Batman Begins was simply going to be a bigged-up print splashed across the centre of the IMAX screen, but then suddenly the frame expanded to fill the whole expanse in front of us, with an establishing shot that felt positively vertiginous. The film would do that again and again, returning to regular widescreen then blowing up again, with a noticeable change in image quality; anyone with a fear of heights should be given fair warning about one particular shot, with Christian Bale in Batman drag standing on the top of the Sears Tower while the camera swings around him, then settles next to him on the ledge. I actually felt a bit queasy myself.

In a summer full of box office monsters, Dark Knight is potentially one of the biggest of them all, and I see no reason to see why it won't. I also see no reason why it was given a PG-13 rating, considering that it's probably one of the darkest films anyone will see all summer - a 2 hour and 32 minute downer delivered at maximum volume and velocity.

It's also goin to get the late Heath Ledger an Oscar nomination, in all likelihood; a lot of pretty astounding things happen onscreen, but his performance is probably the most memorable thing overall. Nolan has managed to do what Ang Lee failed to do with The Hulk - depart from the essential silliness of the comic book film, but mostly by banishing anything resembling levity or satire; it's no surprise that the painted-on smile on Ledger's Joker is the closest thing to humour in all of its 152 minutes.
