Naaah, there's more Speakers here than you would imagine, I suspect.

I first remember reading the short story version (1984?) and was so impressed I started buying O S Card, and have done ever since. There's been a few duffers, but the Ender series has been pretty consistently good.

I'm impressed if they are making a film, but they would definitely need either Paul Verhoeven or Ridley Scott to direct
