The Towering Inferno (1974)
Decided to watch this on a whim and was taken aback. I had no idea this film had such a star studded cast. Paul Newman & Steve McQueen!?! Not to mention Fred Astaire which was a real surprise(oh and OJ Simpson too). Not only did it have a great cast it was also a great film in general. It still holds up today and is a real thrill.
