The cast alone is a mouthwatering prospect, but Glengarry Glenn Ross is superb not just because of the gravitas of its actors, it's the way it's shot, written, and acted too.
I love Jack Lemmon, and surprisingly I'd seen literally one film from his later career (Grumpy Old Men, which was also the first Jack Lemmon film I saw). It was like a beautiful clash of cinematic worlds seeing him chat with Al Pacino.
He's just spellbinding here, the old sparkle of neurotic energy shaped to fit this far more vulgar mould.
Pacino, and Harris get to bark majestically at the quieter Spacey, Alan Arkin gets to play that guy who nods and repeats the other half of a conversation…
