 The "friendly" look continued in Godzillas appearance from 1968 to  1972. Godzilla, by this time, was percieved as the "hero of the  world in his movies instead of an indestructable demon from the  nuclear age. This Godzilla suit went on a diet by being slimmed down  a lot to fit the actor better, and for better mobility while filming  Godzillas battles. Godzillas neck became much longer and his head  more rounded. His pupils were made a little smaller and the width of  his mouth became much longer, traveling down to the upper part of  his neck. His dorsal fins became smaller in size and, like the head,  was also rounded. His two end dorsal fins became much smaller, and  appear as mere little bumps traveling down the back of the suit. The  tail was also made shorter.
