The most recent James Bond film springs to mind.
The most recent three (Die another day, casino, quantum), the main cars were Aston Martin, because Ford up until the filming of the last one, owned Aston Martin, and had the deal to use cars in those films. Thats why the new Ford Mondeo and Ka were also used in two of the most recent ones.
Before those recent three. It was BMW that held the contract to the cars used in the three films before the most recent three.
