I've noticed this when I've listened to other film soundtracks and while listening I was thinking of scenes from ROTF and some themes seemed to match so well as if they could of been used.
In the when Grindor hooks the car that Sam, leo, and Mikaela are in, lifts it up, Sam falls out, gets back in, Grindor takes them to a warehouse, and drops them through the class roof scene, the theme song to Jaws seemed to match so well.
When Optimus is fighting Megs and The Fallen, some of the music from The Rock also matched.
Try it out! Are there any others?
