I have seen many, many bad movies in my time, but without a doubt the absolutely worst movie ever made was The Gauntlet. Pure trash on so many levels. Written by, directed by and starring Clint Eastwood (what do you expect from a guy that made an entire career out of an ability to sneer). I think Eastwood was trying to see if he could produce a movie with a million rounds of ammo be fired. He also found an actress whose acting was actually worse than his. The movie had this ability to keep getting progressively worse. The final scene was incredible. About a thousand cops lining both sides of a street and firing hundreds of rounds (each) of ammo at a bus driven by Eastwood. (Not one cop gets hit by a stray bullet). Then, after Eastwood gets to where he is trying to go, he is surrounded by a hundred cops, shoots the police commissioner, and walks away. Not one cop thinks of perhaps arresting him.
Trash, garbage, crap and pure shit. (Okay I'm being redundant)
