So there he is - a proper pink version of Mark Strong in the original old-school costume. OK, so in the movie Sinestro HAS to be introduced as a good guy and might not even go bad until a sequel (please, let there be a sequel!). So he should probably be wearing the green and black Corps costume, but hey.
Incidentally, the film makers have a couple of serious problems with Sinestro.
1) Characters with goatee beards or moustaches are ALWAYS wrong-uns.
2) He's called 'Sinestro'.
It'll be interesting to see how they handle the good-guy, bad-guy thing.
