I didn't know Jumper was based off of a book.

Jumper  - Steven Gould

Wow, I did not know the movie was based off of a book.  Screw waiting for Jumper 2 I'll just go get all the books :D  I loved that movie and feel like a moron for not knowing it was a book.  All this time I've been waiting for a sequel and there's already book sequels out there.  So happy I could jump for joy.  Pun intended :D
