This is kinda of interesting. According to this story, the new Speed Racer (based on the cartoon) movie is going to use some kind of special camera where "the entire frame always in focus… like a cartoon." Also "they’re also doing two dimensional and three dimensional stuff and mixing and everything is very, very saturated with some new kind of film, so they actually have to treat the actors in some way so we can hold our own with the background."

Now I suppose you could do this with a wide-angle lens, but it sounds like maybe they're doing some kind of compositing to keep all the planes in focus (?) The camera in question comes with "guards"-- anyone know what this might be exactly? Do they mean people guarding the camera? Or is this some kind of camera feature I'm not acquainted with?
