Part of my 70's Disaster Film Weekend! I'll be watching The Holy Trinity of Disaster Pictures from that decade: The Towering Inferno, The Poseidon Adventure, and Earthquake.
As for Inferno?
It's the pinnacle of the 70's disaster craze. A legitimately entertaining and well acted picture that holds up over 40 years after its initial release. With a great story, an amazing cast, and characters you actually care about, modern disaster films could learn a thing or two from this Best Picture nominee.
The entire cast is stellar but I always latch onto Fred Astaire, he's truly wonderful here as a con man with a heart.
