1) James Bond films are frequently bought together on Amazon, though not in any particular order, as the James Bond franchise is one of the most popular action series. 2) When searching for "Action films" on Amazon, Shooter was first and its "frequently bought together" section included Green Zone, suggesting people buy DVDs based on similar actors like Mark Wahlberg and Matt Damon. 3) Green Zone's "frequently bought together" section linked to Hurt Locker and Inglorious Basterds, showing Amazon tries to sell more DVDs by linking unrelated films, though customers who buy action movies tend to only buy within that genre.
