We know you've seen this trailer already (mainly because we showed it to you a couple of weeks ago) but the full Prometheus previews is getting it's TV premiere on Sunday, in the first advert break of Homeland on Channel 4.

And what with nothing being anything without some Twitter validation nowadays, that will be swiftly followed by a second advert made up of Twitter's reaction to the ad, using the hashtag #areyouseeingthis.

Now, we're pretty sure that anyone who cares enough to tweet about it will have seen it already. But it will be interesting to see what a TV audience will make of it - and Idris Elba's not-Stringer-not-Luther accent - and will it be the UK version or the official cinema version that gets shown?

We've posted them both below, let us know which you prefer? (We like the US one better. It's louder.) PS: Here's the Imax trailer , just so we can all get an idea of what we're missing!
