The Towering Inferno (1974)

Previously it was a watery death that an ensemble star cast had to run from, now it's a fiery one. They're opposing elements, but the end result is a similar kind of disaster movie, again produced by Irwin Allen (Dir. John Guillermin).
With a story adapted from two different novels (The Tower by R.M. Stern; The Glass Inferno by T.N. Scortia and F.M. Robinson), the script doesn't rush to the big event, but nor does it dally. An epic establishing scene effectively gets us to where the (hot) shit goes down. Thereafter the two male leads, Paul Newman and Steve McQueen, are cleverly kept apart for the longest time but are dependent on each other's skills at crucial moments throughout.
The villains of the piece are hobnobbing rich folks who feel that their life is somehow worth more than that of the average Joe.
