It's doug.glassman, for pitching his own existing fanfic script in which he would cast Peter Cullen as a Predator. Because if you're going to dream about no financial or creative limits, and get Guillermo to do whatever you want - that's kind of the ultimate exercise of that power.
I've been working on a spec script adapting the "Aliens Vs. Predators" comic "Eternal", and GdT would make an awesome director for it. My version makes it simply a "Predator" film, since the Xenomorphs basically do nothing in the original comic and because the "AVP" film license is sort of toxic at the moment.
If you've never read "Eternal", do it NOW. It's by Ian Edginton with art by Alex Maleev, and you can find it in the first AVP omnibus if you can't find the out of print individual trade. It takes place in the near-future with a hot reporter who discovers a madman trying to capture Predators for his own reason. It brings in the craziest element of Predator lore I've ever seen: if you eat Predator flesh, you become immortal. (Of course, the reason we've never known this in other comics is because no one thinks to stop and eat a dead Predator; they're usually on the run from either other Predators or Xenomorphs.)
"Predator: Eternal" would star Jennifer Lawrence as Becka McBride, Daniel Dae Kim (overdubbed with James Wong's voice) as Gideon Suhn Lee, Ron Perlman as Becka's snarky producer who gets sucked into the whole thing along with her (a character not in the book, but Perlman had to get in there somehow), Doug Jones as at least one of the Predators, and Peter Cullen as the voice of the Predators.
