Ah, I only saw the German dubbed version at the time though they probably used the German actor who does Kevin Spacey's voice. But thinking about it now, there is some of Kevin S in the locust's features.
Sort of like when they turned Jeremy Irons into Uncle Scar.
It wasn't lost on him either. When he was in the studio dubbing his parts to the animation he commented:
"Oh, I see, you have drawn me as a lion!"
