There was an article in the National Post earlier this week describing how The Black Knight's immense popularity is helping to lift the fortunes of beleaguered Canadian 3D theatre operator IMAX. Not only is the box office moola spilling over to IMAX's screens, Batman seems to be reintroducing movie-goers to an experience they left years ago - not because it wasn't impressive but because the films themselves (usually of the nature documentary variety) were stuck in a bit of a rut. But nothing quite beats a caped vigilante jumping off a Gotham skyscraper or a disheveled joker (masterfully!) robbing banks and blowing stuff up.Another film to also inject some 3D life into an already energetic genre is U2's recently released concert video U23D. It's a stunning production - the first digital 3D, multi-camera, real-time shoot; the largest collection of 3D camera technology ever assembled for a single project. As a fan of both rough concert bootlegs and polished concert videos, this film takes it all to a whole other level. It eclipsed simply being a recording and instead felt like an outing; being amongst the buoyant Argentinean crowd (an inspired venue choice), right next to Adam's drum kit, and probably closer to Bono than is really necessary. No doubt other (relatively wealthy) bands will follow. In the meantime, don't miss donning the special visors for this one.
