After languishing in a customs shed for a month under the eye of some Iberian jobsworth my travel bike has finally arrived in Barcelona. By 9 a.m. I am climbing the slopes of Montjuic for the second time this weekend to check out tomorrow’s locations. I spent yesterday sketching out the scenes we will shoot here tomorrow and I realise I will have to revise my ambitious plans. I finish drawing at 930pm and I’m exhausted. I have made the classic error of tiring myself out trying to plan the week ahead by storyboarding every scene instead of relaxing. Seven hours before tomorrow’s call I find myself in the Pizza Hut 100 yards from Sagrada Familia wondering why I am doing this to myself.
