Two European documentaries from 2005 about the construction of two large, innovative, and controversial buildings. Fredrik Gertten’s 59-minute The Socialist, the Architect, and the Twisted Tower, in English and subtitled Swedish, concerns the Turning Torso, a residential high-rise by Spanish architect Santiago Calatrava in Malmo; it has the more interesting subjectconflicts between class and aesthetic issuesbut the filmmaking is dull. Dutch director Mirjam von Arx’s 52-minute Building the Gherkinin English, about Norman Foster’s pickle-shaped office tower on the site of an IRA bombingis something of an industrial, but it’s an adept and entertaining one.
