The Towering Inferno is the best execution of the disaster formula of the 70s. Get an all-star cast and put them into a B-movie disaster scenario. In this case it's a massive fire in a recently constructed skyscraper. The developer (William Holden) cut corners which allowed the fire to start. His son in law (Richard Chamberlain) was an electrical subcontractor for the building. Paul Newman is the architect that designed the building, Steve McQueen is the fire chief who arrives at the scene, yada yada. The back story isn't really that interesting. The main attraction is the disaster, and although it's a bit of a slow burn in the beginning, things soon heat up (ok no more fire puns). The set pieces and action sequences, all made with very good practical effects, still hold up today. Nothing feels cheap about it. And the cast is good enough to keep the movie going along unlike The Poseidon Adventure where stars Gene Hackman and Ernest Borgnine play guys who just yell all the time. Paul Newman and Steve McQueen are, in a word, cool. They aren't just A-list actors, they're stars. None of the disaster movies had the star power this movie has. The supporting cast of William Holden, Faye Dunaway, Fred Astaire, etc. is also impressive. Richard Chamberlain in particular is great, it's impossible to like him at all. And that's where The Towering Inferno succeeds. It's the most engaging, least hammy of all the disaster films in the 70s, and it is worth the watch.
