Hwood films that teach you all about corruption. Blackmailing politicians is big business, and is at the core of this 1981 Bran DePalma film titled Blow Out, starring John Travolta. Yes, he's a lunatic. Most of them are, but if they can dramatize reality, then thank you lunatics. Enjoyable for old school film making, and a solid, believable story of how political corruption and control works. Free with ads viewing.
