This is a very funny political satire that was very topical back in the 1970's but will probably seem rather unfathomable to contemporary audiences who have no idea who Howard Cosell, Roger Grimsley or even Fidel Castro and Che Gueverra were. I nearly collapsed with laughter in the subway scene featuring a then unknown Sylvester Stallone as a thug beating up an old lady sitting next to petrified Fielding Mellish pretending to be absorbed in his magazine. One thing I should note: every time this film appears in NYC, there is a publicity shot in the newspapers showing Fielding Mellish (the Allen character) interrogating a parrot at his trial (inspired by the Chicago Seven Trial a few years earlier). This scene was not in the film when I first saw it when it came out or any viewing since, and I have seen it many times.
