Actually, with regard to "First Blood", that's one of those movies I think would be prime for my two-films-remade-into-one idea...if you mixed it with, say, "E.T.": an alien gets accidently left behind on Earth and befriends a young boy and his siblings, but when the Feds bear down on the family to get to him, he leads the military on a hunt into the nearby woods in which THEY quickly become the hunted.
Failing that mindset of remaking films, though, I still want a retro-'30s/'40s Superman movie, with some giant damn robots and death-rays and jet-pack-wearing gangs for once instead of General Zod and Insert-Evil-Kryptonian-Clone's-Name here, and (if we have to have him again) a big-screen Lex Luthor who's NOT yet another goofy dip****.
