Kind of Like a Bond Film
The movie has all the elements of a good Bond film. This movie could be remade into a modern movie and it would work well. It would work very well as a Bond movie (villian forms a group that sells arms to terrorists). You have a villian, a bond girl that has a connection to the villian, a secret lair, the villian dining with good guys and so on. I think it would make a really great movie nowadays.
I also thought that this movie had a very fast pace for a movie of its era. I've seen newer movies that were slower paced than this one. It really is great.
