It seems that due to a rather manual online booking system the Curzon cinema group have given me the wrong ticket - Steamboy on Saturday at 4:15pm. It's now sold out and has a Q&A after. It's going spare until tomorrow evening when I shall be swapping it for the ticket that it's meant to be - the not sold out Machinist, with Christian Bale looking very ill.
Ticket 8 quid, 4:15pm, Curzon Soho.
