J.J. Abrams Admits Star Trek Lens Flares Are "Ridiculous" (made w/ flashlights)

"...The flares weren't just happening from on-camera light sources, they were happening off camera, and that was really the key to it. I want [to create] the sense that, just off camera, something spectacular is happening. There was always a sense of something, and also there is a really cool organic layer thats a quality of it. They were all done live, they weren't added later. There are something about those flares, especially in a movie that can potentially be very sterile and CG and overly controlled. There is something incredibly unpredictable and gorgeous about them. It is a really fun thing. Our DP would be off camera with this incredibly powerful flashlight aiming it at the lens. It became an art because different lenses required angles, and different proximity to the lens. Sometimes, when we were outside we'd use mirrors. Certain sizes were too big... literally, it was ridiculous. It was like another actor in the scene...."
There's a brief Youtube video included demonstrating the camera effects.
