I think the Indian poster is terrible. It's not a bad idea – I can go with that – but the execution is very poor.
Didn't we see a very similar image with the original Entertainment Weekly story? At that time I thought it was something that the magazine's designers had photoshopped which would account for its poor quality; the perspective is out and the proportions between the figures and urns are clearly wrong.
That said, foreign move posters are often left to the discretion of the marketing teams in those territories and may well appeal to people in those countries – remember the famous Alien posters from Poland?

Unlike the 70s or 80s, anyone can do a lash-up in Photoshop and I think that's one of the reasons you see so much dodgy artwork these days. Personally, my fave poster so far is still the teaser. And that, let's face it, is nowhere near as mysterious, memorable or engaging as the poster for Alien. Hard act to follow...
I'd like to see a new poster for Prometheus. Avatar had a minimalist teaser and then a few variants for the movie's release. I'd like to see the same treatment for Prometheus.
