Martin Scorsese and Robert De Niro. Harrison Ford and George Lucas. Tim Burton and Johnny Depp. Those you know. Now how about Russell Crowe and Ridley Scott? The duo has teamed up for four movies, one of which, Gladiator, is an outright classic. Something about Scott's muscular directing style and Crowe's gruffness works time after time. (When they toned it down for A Good Year, audiences were lukewarm.) Test your knowledge of Scott and Crowe's collaborations in honor of their latest, Body of Lies. Time will tell if they reach the heights of De Niro and Scorsese, but for now, they make a pretty solid team.
