6. Glengarry Glen Ross

The ultimate ensemble movie, written by and based on David Mamet’s play of the same name, Pacino stars alongside the likes of Ed Harris, Alan Arkin, Kevin Spacey, Jonathan Pruyce and Jack Lemmon as the top performing real-estate salesman in an under-pressure office. Alec Baldwin plays Blake, sent by corporate bosses to shake-up the team.

Monologue-heavy, with some of cinema’s biggest beasts competing for attention, Pacino nevertheless shines as Richard Roma. The role garnered Pacino yet another Supporting Actor nomination at the Oscars. He was beaten by Gene Hackman as Little Bill Daggett in Clint Eastwiod’s Unforgiven but the disappointment was probably saved by his winning the Best Actor OScar for Scent of a Woman.
