Dog Day Afternoon (1975)
Sometimes, as we see in Sidney Lumet's spectacular, almost cordoned-off masterpiece, heists can go wrong.
Based on a newspaper article about a simple bank robbery going very wrong, Dog Day explores a confined space and works its magic as a volatile police-media situation is straddled by bank robbers who have bitten off far more than they can chew.
The political and social ramifications are immense, and the film boasts of Al Pacino's greatest performance.
