In the movie, Herzog explains his jealousy that the fact that his office had worked in London before ruled them out of the Serpentine commission - which goes to architects that have never built before in the UK - and his delight at the ruse employed by the Serpentine Gallery to get around this: by teaming up with Chinese artist Ai Weiwei, their co-collaboraotor on the Bird's Nest Stadium in Beijing, to form a team that satisfied the rules.
Herzog also explains why they decided to bury the pavilion in the ground beneath a raised pool of water and why they based the design on the imagined archaeology of the previous pavilions that had occupied the site.
