Ok, when I ordered the ticket there was NO information about screenings of Prometheus and Alien Directors cut. It just said Alien: Covenant, (just like in a screen shot a few posts up). This was found by just going into the 'Coming Soon' section of the VUE website. It advertised the tickets at the time of booking as being Alien Covenant, I message VUE to confirm this was a advance showing and they actually confirmed this... Then a day later I tweet them when i started reading that its not what I thought it was and in fact a double bill of Prometheus and Alien. They message me back saying exactly what some of you guys found out... so yeah very misleading.
We still get Alien Covenant early... just a day though. The 10th.
