This is how Michael Bay saved money on making the Transformers. The top image is from the movie Pearl Harbor, while the bottom one is from Transformers. All they had to do was CG out the old looking stuff and make it new looking. This probably saved him, i don’t know 10 million dollars. I don’t know about that, i just pulled that number out of my ass.
I know that the guys who did Scratch used footage from there movie American Pimp. I always thought that was interesting.
