But it's far more likely that the movie's designers just went their own way. As I suggested before, given how widespread the dislike of the old trunks-over-tights designs are these days, it's not even slightly implausible that two designers working with absolutely no knowledge of each other's designs would've made the same decision independently. So that particular similarity is not evidence of direct influence. If there were a similarity that weren't
something one would've naturally expected anyone in the present day to have come up with -- like, say, if they'd both added a fur lining to the cape or put spurs on the boots -- then you could reasonably surmise a direct influence, because that's unlikely to be the result of coincidence or generational shifts in taste. But the loss of the trunks is not sufficient evidence of that.
