Just read this article that Latino Review is reporting that Harrison Ford is "in" for Episode 7:
Cool! I don't see how they can avoid getting Luke/Han/Leia into E7 at least, so great to here progress on getting the original actors. Of course, I'm not sure the "Latino Review" is where I'd expect to find breaking news on Harrison Ford or Star Wars...
El Mayimbe is pretty spot on in everything he posts. Latino Review is pretty good at confirming stories before posting. They are well respected.
