I’ve been known to call someone “an old ulsio” on occasion.
If I remember, those are the ground hog sized multi-limbed Barsoomian rats.
Another thing is these books had some of the best imagery ever, and Frazetta and Mike Whelan captured that in the art they did for the various paperback editions. The trailers makes it look like some Earth desert—it has been years since I read them though, so maybe that is the way it was in the books, but man that is not what I have been picturing all these years. Maybe because of the artwork I’ve seen. The director is the guy who did Wall-E so I am thinking it might be pretty good.
