Re: Peckham
As in the Peckham Multiplex? Ha. That's my local. You're in for a treat. Be warned, patrons of the 'Plex tend to enjoy shouting along at the screen. As in, proper shouting. Especially during any quiet bits (I noticed they were showing The Artist there, so god knows what that must have been like).
I haven't been for years as I found the interaction quite grating after a while (although seeing Mean Girls on a matinee viewing was a laugh). It used to be £3 for any film, any time, which made the experience bearable. But since the price went up to a fiver I now opt to get the bus to the hoighty toighty Greenwich Picture House instead.
