The trailer for the Godfather was very weak, but that was the way most of the trailers in the 70's were like. Don Mataya said people will know what was going to happen, but remember, the Godfather was the highest selling book in the 70's and most people had read the book already. So the content of the movie didn't matter to the fans. But I have to admit, it did start getting really dumb when it showed Sonny's death on the causeway.
But how about that Godfather II trailer. Is that good or what. I get chills watching it. That is one of the best trailers I have ever seen. Godfather III's is pretty damn good too.
