Question: Which documentary premiered first, Life in the Undergrowth or Sketches of Frank Gehry?
Context: Sketches of Frank Gehry is a 2006 American documentary film directed by Sydney Pollack and produced by Ultan Guilfoyle, about the life and work of the Canadian-American architect Frank Gehry.  The film was screened out of competition at the 2006 Cannes Film Festival.  Pollack and Gehry had been friends and mutual admirers for years.  The film features footage of various Gehry-designed buildings, including Anaheim Ice (the training rink of the Mighty Ducks of Anaheim), the Guggenheim Museum Bilbao, and the Walt Disney Concert Hall.  It was the final film to be directed by Sydney Pollack before his death in 2008. Easy Edges is the name given to a series of furniture designs by Frank Gehry from 1969 to 1973.  These early designs were partially responsible for Gehry's rise to public recognition in the early 1970s.  After discovering that corrugated cardboard layered enough times in alternate directions builds strength into the piece and make it suitable for the everyday use, Gehry created a series of pieces of furniture such as the "Easy Edges Wiggle Side Chair" that take advantage of the versatility of cardboard as a medium.  Hardboard facing is applied to the furniture's flat surfaces to add to the durability of the designs.  Gehry's use of cardboard as a medium demonstrates his "fundamental concern with manipulating basic materials in unconventional ways to produce objects that are functional yet also visually striking". Life in the Undergrowth is a BBC nature documentary series written and presented by David Attenborough, first transmitted in the UK from 23 November 2005. Gehry Tower is a nine-story building constructed by architect Frank Gehry; it is located at the "Steintor", Goethestraße 13a, in Hanover, Germany.

Designed by Pritzker Prize-winning architect Frank Gehry, it opened along with the rest of Millennium Park on July 16, 2004.

It was originally an extension, designed by Gehry and built around an existing Dutch colonial style house.  It makes use of unconventional materials, such as chain-link fences and corrugated steel.
