I used to read Wolverine comics as a kid, but never got into his origin too much before I outgrew them. I just saw this movie with my own kid, liked it, but I;m curious. How faithful is this to the origin as told in the comics? What are the major differences?
I never knew Wolverine and Sabertooth were brothers, is that made up for the film? Also, was there a "Weapon XI" in the comics? Any other major discrepancies?
Thanks for helping to satisfy my curiosity!
