Towering Inferno.
Horrible Movie. Completley campy acting with an implausable plot. Chock full of 60's/70's movie stars and faces that make you say, "isn't that the guy from that one movie.......". The end of the movie is classic frontier gibberish mixed with full-on sillyness with a touch of 'oh no he didn't'.
But I love it. Watch it every time its on.
