Quote from Woody in The Last Picture Show
Cliff: So, uh, what'd I miss? Why- Why is that girl, uh, running around screaming at everybody? Norm: Well, she's trying to convince them that, uh, that Godzilla's merely confused and not really trying to hurt them. Cliff: Isn't that the part usually played by Akiro Nakamoto? Norm: Yeah, yeah. But, uh, she left halfway through the Godzilla series. Woody: I don't understand. Why would an actress leave right in the middle of a successful series?
