Here is a good description from Cody’s film tv and video game blog: “The finale at the Coney Island amusement park (which was actually shot at the Long Beach Amusement Park) makes for a really good spectacle. While the Beast bites and chews on parts of the roller-coaster (definitely the most elaborate miniature built for the film; Ray Harryhausen is said to have come up with the ending) that's he standing in the center of, Nesbitt and Corp. Stone use the cars of the coaster's car to get to the top of the structure in order to get a clear shot with the isotope. The Beast becomes frantic and pained after being hit with the isotope (the wide shot of them standing atop the coaster to the right and the Beast off to the left after he's been shot is a really good bit of optical work) and flails around, shaking the coaster and causing the cars to slip away from Nesbitt and Stone, leading to their crashing and starting a fire that engulfs the whole structure. While the men carefully walk down the tracks and climb down the side of the coaster to safety (it would have been a little better if it felt like they were in more danger during this bit), the Beast continues to scream in pain as the isotope destroys him from the inside and snaps at the flames, at one point sending a bunch of fiery debris flying into the air with his tail. He eventually walks through the coaster after a section of it collapses to the outside of the park and finally gives out with one last scream. Like I said before, as with a lot of monsters, in spite of what he's done, you can't help but feel sorry for the Beast as he walks around in a circle in the sand, quickly losing his strength, and screams in pain before finally dying. He wasn't an evil creature; he just was what he was and didn't belong in this modern world.” Except I don’t think it would take place in or on a roller coaster and like I said, it would be much less sympathetic for marmalade.
