SpaceBallz wrote:A recent documentary on Ghostbusters (Cleaning up the town, maybe?) had one of the f/x guys state that they misinterpreted the desired "rubber band" proton stream effect; if you look closely in some of the proton stream scenes in GB1 you can see that they shoot the "rubber beam" out and the stream jumps back into the wand when they activate it again, like the beam has a life of it's own. I think they rectified it in GB2 and opted for more of the lasso effect.
In the SFX Team Featurette, Terry Windell said, "And actually took explosions that were filmed on the stage and then rephotographing them with a technique that these guys called pin blocking so we can miniaturize these little explosions so that the tip of the gun had pyrotechnic explosions and flares and things laced in there with five levels of classical animation that was also manipulated on the optical printer by Mark Vargos."
In Slimer Mode on the Ghostbusters Blu-ray, 36:33-36:59, Richard Edlund said, "And so we came up with an animated style for the neutrona wands, where the beam would shoot out and it would hover. And it was funky-looking, but very kind of funny. And there was something about it. We talked about rubberizing light. It wouldn't have been funny if it had just been a straight beam. It's like a laser beam. Everybody's seen that already."
Then at 36:26-36:32, John Bruno says, "And I said, "They'll never point them in the right place so let's just make it crazy, so that once it's connected, it's like a fishing line."
Then at 37:00-37:16, Terry Windell says, "We wanted a certain amount of warmth and we ended up using contrasting colors. So we had this sort of amber orange glow and then we wrapped it with, you know, cool blue electricity. So, you sort of had the whole spectrum in there."
Then of course for GB2, a different team, ILM did the SFX rather than the Boss team returning. At first, they did try to copy the look but then the leads encouraged them to try a different look.
- In Cinefex magazine #40, page 18, Tom Bertino says: "The animated nutrona beams in the first film looked really good and initially we tried very literally to duplicate that look. But then Dennis and Mark Vargo encouraged us to have fun with the beams. We all figured that since people have already seen what the beams could do in the first film, the surprise was off. We needed to take them in a new direction. For instance, in the courtroom, the beams act like cowboy lassos or fishing lines, reeling the ghosts in. The beams catch the Scoleri brothers around the ankles, then the ghosts slip through and and beams wrap around their necks. John Armstrong and Peter Crossman did a great job of animating these shots so that the beams almost seem to have a consciousness of their own. When first suggested these ideas to Dennis and Mark, they liked them. Then we sent pencil sketches down to Ivan and sat with our fingers crossed because we really wanted to get these ideas into the movie."
Then on page 20, Dennis Muren says, "I think the lasso was a pretty neat concept that worked well with the squash and stretch effects we were creating with the mirrorplex. Then we thought that if we could line up the mirrorplex and squeeze the ghosts when the nutrona beams wrapped around them, it would show a more direct effect from the beams. One of our animators came up with the next step on that, which was a very obvious lasso that starts wrapping around one of the brothers and then pulls him tight, squeezing him in the middle. It was just wonderful. Anything that had that kind of character was something we really liked."
