I doubt it is more known than SpiderMans origins and outside of Smallville and the late 90's cartoon, his origins hasn't really been told that much. There are much, much more Spiderman cartoons from 2000 and upwards and 2 origin films were made in the span of ~10 years. I'm interested in Snyder/Nolans (Christophers brother that co-wrote TDK & TDKR) take on the origins. Plus they hired Crowe as Jor-El so it'll be interesting how things go in this version. I really, really do not mind a new Superman origins at all. I welcome it much more than the Spiderman origins, it just has to be down right.
