So the question is, are there any live-action kaiju-vs.-mecha motion pictures, other than Pacific Rim
, in which the mecha (and their operators) are treated as the "stars" rather than the kaiju?
Well, the two Power Rangers
feature films seem the clearest examples. And of course in Japan the Super Sentai
franchise, from which PR is adapted, releases movies fairly regularly, usually featuring crossovers between Sentai teams from different TV seasons.
