What was the no. 1 movie in July of 1975?

The answer is: Jaws. Before 1975, the concept of a summer blockbuster didn’t really exist. But when Jaws came on the scene in late June, everything changed forever.Not only did Spielberg’s breakout hit dominate July, but it was also number one all the way through September. Everything that came after has simply been trying to recreate the summer of 1975.Source
