I'm in doubt. NOTHING about him looks like Jack excpet for dreads and the beard but his eyes? his face? the expression? If it's Jack then he's not his usual self. He doesn'thave that Jack-ness.
It COULD be Teague! But I highly doubt it. Since there's no other possible option it might be Jack but something just feels very...off.
We really have to wait and see the scnerio they put Jack in. It's only for a short while cause I'm 100% sure that (as u saw in the trailer) Jack's as human as ever in the brethern and the purgatory etc.
No worries.
it's definately Jack.
I don't think it's him in disguise either. i would maybe go with the theory that its just Jack hallucinating in purgatory, but i also have strong imaginative suspicions that it is part of some deep and unresolved plot towards the end when everyone is dying and going immortal and such. it's either got to be towards the beginning or end of the film.
a couple of things. thing 1: remember in the first film when jack turned into a skeleton dude at the end for a few minutes? couldn't resist--- just as the screenwriters couldnt resist having that much digital fun with their leading man. now we've seen fish-faces and crusty men, but not on the leading man! thing 2: it is the briefest, 2 frame shot... akin to the briefest flash of the curiosity almost-kiss in the trailer for 2. only the very perceptive catch it, though it ends up having an unexpectedly meaningful time in the film. make sense?
