This reminds me, we meant to go and see "300" on the IMAX at the Metreon, but this time with good seats, and we never did. I suspect it's gone from there now. D'oh! Oh well.
Oh, and on the topic of spoilers for "300", a colleague, mcl, said: "I suggest you avoid Book VII of herodotus' The Histories if you want to avoid spoilers." Hehe.
