Michael Bay Reuses a Scene from THE ISLAND in TRANSFORMERS 3

This would be the first time Michael Bay reuses footage from previous film and throws it in a Transformers movie. The first time was when he took a shot from Pearl Harbor of an Aircraft carrier and used it in the first Transformers film. The reason for this is to save money on these very expensive films. I just came across this clip on /Film that shows another recycled scene from Bay's The Island that was used in the latest Transformers film. It's cool to see what they can do with these scenes by just adding some awesome special effects to it. I wonder how much this happens in movies that we miss.
