The new flick 500 Days of Summer, which generated much buzz as the 2009 Sundance Film Festival, rolls out in limited release today. Lot’s of people are talking about it as a romantic comedy meets Momento which in film terms means that those with ADD or short attention spans might be confused by this rambunctious romantic romp. But for us, the buzz doesn’t just lie in the zigzagging sex talk but rather in the architecture talk. Even more specifically in the Green architecture talk.

Now Tom Hansen, (Joseph Gordon-Levitt) isn’t exactly Howard Roark but his some of the film’s core revolves around Hansen’s progressive architecture thinking. Even more he talks about density in Los Angeles as he admires Pershing square. Density in Los Angeles of all places. We can hardly stand it.

Even later in the film after the romances goes South, Hansen picks up a Green architecture book and delves into it. Maybe this film won’t be an LA Story or When Harry Met Harry film for the ages but now we have sustainable architecture thinking sneaking into progressively solid romantic comedies. For us, that’s better than a tub of organic popcorn and a soda without high fructose corn syrup.
