Seems there was a lot hidden in this video - good job everybody! Sorry I haven't had chance to try and contribute to this.
On an unrelated note, I've got to say that teaser left me a little underwhelmed. For one of the first major bits of SW8 marketing, I felt there was a lot to be desired. I think it felt a bit badly acted at some points, especially seeing as they've paid extra to get an (admittedly fairly obscure) celebrity in. Also I didn't really understand what kind of audience they were aiming at - it almost felt like a CBBC show, which is a bit odd assuming The Welcoming (a scare-maze with a linked in theme) has a fairly dark and sinister vibe. I just felt this was nowhere near as strong of a start as the Smiler and DBGT marketing campaigns had when they released their first videos. Rant over.
