The shadow government which actually controls the nation and seized power by assassinating JFK cannot and will not allow the full truth regarding LBJ to come to light. Why anyone (Rob Reiner?) would want to make a guaranteed historically inaccurate movie about a portion of this evil man's life escapes this scholar of history.

LBJ was one of the most corrupt politicians in the history of the Republic starting with the Box 13 Scandal which "elected" him to the Senate to the government contract known as the TFX/F-111 tactical fighter project which had been awarded to Boeing by virtue of its low bid but Johnson had switched to General Dynamics because the main plant was located in Texas and as a result of a $100,000.00 bribe paid to Johnson.

LBJ employed his own hitman, Malcolm "Mac" Wallace, an individual not named in Robert Caro's exhaustive and seminal four volume biography of Johnson which is surprisingly accurate for the most part. Many murders took place on orders from Johnson in order that his corruption not become known. Johnson even had his Bohemian life-style loose-lipped sister killed. A fingerprint of Mac Wallace was lifted from inside what is commonly referred to as the Texas School Book Depository. Wallace was one of the shooters.

How ironic that Woody Harrelson would play the man that set the assassination plot in motion since his own father, Charles Harrison was an organized crime figure who was convicted of assassinating a federal judge and was imprisoned. While in prison, a video exists of Harrelson admitting his participation in the plot that assassinated JFK.

To the OP, my politics are very-left wing including socialist positions, some of which The New Deal incorporated as governmental responsibilities. I am not however a Communist, a form of government doomed to failure by the very nature of mankind. And, BTW, LBJ was a huge racist blocking President Kennedy's racial reform legislation to save for his own administration and to become a part of his own legacy.
